This section provides an overview of the key steps for installing Red Hat Enterprise Linux so you can get started with software development. Note: This tutorial does not replace the Red Hat Enterprise Linux Installation Guide. Instead, this tutorial provides an overview of the key steps for software developers. For detailed instructions, see the respective manual.

A few things to keep in mind:

  1. The Red Hat Enterprise Linux Server .iso you downloaded in step 1 will be used to install a system with a full graphical desktop. You will select Server with a GUI under Software Selection during installation. By default, Red Hat Enterprise Linux Server will not install a graphical desktop.

  2. You will need to select an Installation destination, which is the disk or partition(s) where the software will be installed. The disk or partition(s) you select will be overwritten. Make sure you understand your selection before starting the installation to avoid accidental data loss.

  3. You should configure networking under Network and host name before starting the installation. You will need access to the Internet to complete registration and download additional software. The network can be configured after the system is installed. However, the steps are more straightforward during installation.

  4. Create your primary user account during installation: After the installation begins, you will be instructed to set a password for the root account and be given the opportunity to create a regular user account. You should create a user before the installation process completes. The regular user will be your primary login for development. The root account should only be used for system administration tasks. If you don’t create a user before the installation completes, you will need to reboot and then log in as root to create user accounts.

System Requirements

The requirements for your physical system are:

This step provides an overview of the key steps for installing Red Hat Enterprise Linux Server in a Hyper-V Virtual Machine (VM) so you can get started with software development. The VM you create will give you a Red Hat Enterprise Linux development environment that you can use on your system running Microsoft Windows 10, 8.1, or 8.0.

Overview of steps

  1. Enable Hyper-V

  2. Configure a VM to run Red Hat Enterprise Linux.

  3. Boot the VM using the ISO file you downloaded in step 1 as a virtual DVD.

  4. Install Red Hat Enterprise Linux.

Note: This tutorial does not replace the Red Hat Enterprise Linux Installation Guide or Microsoft Hyper-V documentation. Instead, this tutorial provides an overview of the key steps for software developers. For detailed instructions, see the respective manual.

A few things to keep in mind:

  • You will be using the Server edition of Red Hat Enterprise Linux. This provides you with the widest range of software to develop and test with.

  • The VM will have a full graphical desktop. You will select Server with a GUI during installation.

  • After installation, you will configure additional software repositories that will provide you access to optional development software such as RHSCL and DTS.

System Requirements

The requirements for your physical system that will host the Red Hat Enterprise Linux VM are:

  • a 64-bit x86 machine with hardware virtualization assistance (Intel VT-X or AMD-V) and Second Level Address Translation (SLAT).

  • Microsoft Windows 10, 8.1 or 8.0.

  • 4 GB RAM (8 GB preferred).

  • 24 GB of available disk space for the VM, the installation ISO file, and Hyper-V.

If you encounter difficulties at any point in this tutorial, see Troubleshooting and FAQ.

Enable Hyper-V

This guide shows the steps for Hyper-V on Windows 10 Professional. The steps Windows 8 and 8.1 are similar but may have small differences. Hyper-V is installed, but not enabled by default on most editions of Windows starting with Windows 8.

To enable Hyper-V the Hyper-V role:

  1. Right click on the Windows button and select Programs and Features

  2. Select Turn Windows Features on or off from the sidebar on the left.

  5. Close the Programs and Features window.

For more information see Install Hyper-V on Windows 10 or consult the documentation for your version of Microsoft Windows. Note: some of the Hyper-V documentation may be listed as "Client Hyper-V" since Hyper-V was originally a server feature.

Enable Intel VT-x or AMD-V Virtualization in BIOS/UEFI

Intel and AMD processors have hardware extensions for accelerating virtualization. On some systems this support may be disabled by default in the system’s BIOS/UEFI. To enable the extensions, you might have to go into the system’s BIOS/UEFI setup configuration at boot time. Consult your system’s hardware documentation for more information.

Create and configure a VM in Hyper-V

In this step, you will create and configure the VM that will run Red Hat Enterprise Linux. The physical system you are running Hyper-V on is called the host system or root partition. The VM is called the guest system or child partition.

First, launch Hyper-V Manager from the Windows menu.

Install the latest updates

In this step, you will download and install the latest updates for your system from Red Hat. In the process, you will verify that your system has a current Red Hat subscription and is able to receive updates.

First, start a Terminal window from the Application menu. Then, after using su to change to the root user ID, use subscription-manager to verify that you have access to Red Hat software repositories.

$ su -
# subscription-manager repos --list-enabled

If you don’t see any enabled repositories, your system might not be registered with Red Hat or might not have a valid subscription. See Troubleshooting and FAQ for more information.

Now download and install any available updates by running yum update.

# yum -y update

Enable additional software repositories

In this step you will configure your system to obtain software from the Optional RPMs and RHSCL software repositories. The Optional RPMs repository includes a number of development packages. The RHSCL repository includes the both the RHSCL software collections as well as DTS (the Red Hat Developer Toolset).

# subscription-manager repos --enable rhel-server-rhscl-7-rpms
# subscription-manager repos --enable rhel-7-server-optional-rpms

Finally, reboot the VM. You can do this from the VM’s desktop by clicking the down arrow icon in the upper right corner, then clicking the power icon. Alternatively you can reboot the system from the command line:

Body

This step provides an overview of the key steps for installing Red Hat Enterprise Linux Server in a Virtual Machine (VM) running on your Linux system using KVM/libvirt virtualization. The VM you create will give you a Red Hat Enterprise Linux development environment that will run on Fedora, CentOS, Ubuntu, or other Linux. Instructions are shown for Fedora 23 and Ubuntu 14.04, however these steps should work on other Linux distributions that include KVM and libvirt tools including virt-manager.

Overview of steps

  1. Install KVM and libvirt tools

  2. Configure a VM to run Red Hat Enterprise Linux.

  3. Boot the VM using the ISO file you downloaded in step 1 as a virtual DVD.

  4. Install Red Hat Enterprise Linux.

Note: This tutorial does not replace the Red Hat Enterprise Linux Installation Guide or your system’s virtualization documentation such as the Fedora Virtualization Getting Started Guide. Instead, this tutorial provides an overview of the key steps for software developers. For detailed instructions, see the respective manual.

A few things to keep in mind:

  • You will be using the Server edition of Red Hat Enterprise Linux. This provides you with the widest range of software to develop and test with.

  • The VM will have a full graphical desktop. You will select Server with a GUI during installation.

  • After installation, you will configure additional software repositories that will provide you access to optional development software such as RHSCL and DTS.

System Requirements

The requirements for your physical system that will host the Red Hat Enterprise Linux VM are:

  • a 64-bit x86 machine with hardware virtualization assistance (Intel VT-X or AMD-V).

  • 4 GB RAM (8 GB preferred).

  • 24 GB of available disk space for the VM and the installation ISO file.

If you encounter difficulties at any point in this tutorial, see Troubleshooting and FAQ.

Enable Intel VT-x or AMD-V Virtualization in BIOS/UEFI

Intel and AMD processors have hardware extensions for accelerating virtualization. On some systems this support may be disabled by default in the system’s BIOS/UEFI. To enable the extensions, you might have to go into the system’s BIOS/UEFI setup configuration at boot time. Consult your system’s hardware documentation for more information.

Install KVM and libvirt tools

Install the KVM and virtualization tools for your Linux system. Then, start libvirtd.

Fedora 23

$ su -
# dnf install @virtualization
# systemctl enable libvirtd
# systemctl start libvirtd

Check that libvirtd is running:

# systemctl status libvirtd

Optionally, add your user id to the libvirtd group to enable running KVM virtualization without being prompted for a passowrd. If $USER doesn’t contain your username, enter your username instead:

# echo $USER
# usermod -a -G libvirt $USER

Note: you will need to log out and back in again for the group change to take affect.

CentOS 7

$ su -
# yum install @virtualization
# systemctl enable libvirtd
# systemctl start libvirtd

Check that libvirtd is running:

# systemctl status libvirtd

Optionally, add your user id to the libvirtd groups to enable running KVM virtualization without being prompted for a password. If $USER doesn’t contain your username, enter your username instead:

# echo $USER
# usermod -a -G libvirt $USER

Note: you will need to log out and back in again for the group change to take affect.

Ubuntu 14.04

$ sudo -i
# apt-get install qemu-kvm bridge-utils libvirt-bin virt-manager virtinst virt-viewer

Check that libvirtd is running:

# /etc/init.d/libvirt-bin status

Optionally, add your user id to the libvirtd group to enable running KVM virtualization as a non-root user. If $USER doesn’t contain your username, enter your username instead:

# echo $USER
# usermod -a -G libvirt $USER

Note: you will need to log out and back in again for the group change to take affect.

Create and configure a VM

In this step you will create and configure the VM that will run Red Hat Enterprise Linux. The physical system you are running KVM/libvirt on is called the host system. The VM is called the guest system.

Instructions are provided for creating the VM using the virt-manager or from the command line using virt-install.

Using virt-install (command line)

Use the following command to create a VM and start installing Red Hat Enterprise Linux.

Fedora 23 and CentOS 7:

Note: you need to run virt-install as the root user.

# virt-install --name rhel --ram 2048 --disk size=20,format=qcow2 --vcpus 2 \
       --cdrom rhel-server-7.6-x86_64-dvd.iso \
       --virt-type kvm --os-variant rhel7 --graphics spice

Ubuntu 14.04:

$ virt-install --name rhel --ram 2048 --disk size=20,path=$HOME/rhelvm.sda --vcpus 2 \
       --cdrom rhel-server-7.6-x86_64-dvd.iso \
       --virt-type kvm --os-variant rhel7

After creating the VM, virt-install will automatically start virt-viewer to give you access to the VM’s console. Proceed to Install Red Hat Enterprise Linux.

Using the virt-manager GUI

To create a VM using the virt-manager GUI, start Virtual Machine Manager from the system menu or enter the command virt-manager.

  1. When virt-manager opens, it will show the available hypervisor connections. If you don’t see QEMU/KVM listed:

    1. Select New Connection from the File menu.

    2. Select QEMU/KVM from the list of hypervisors.

    3. Click Connect.

      Screenshot KVM Add connection

  2. Select New Virtual Machine from the File menu.

  3. On the Create a new virtual machine dialog:

    1. Make sure Connection is set to QEMU/KVM.

    2. Select Local install media (ISO image or CDROM) under Choose how you would like to install the operating system.

    3. Click Forward.

      Screenshot KVM VM Create

    3. Uncheck Automatically detect operating system based on install media.

    4. Set OS Type to Linux.

    5. Set Version to Red hat Enterprise Linux 7. If that choice is not available, you may select Red Hat Enterprise Linux 6.

    6. Click Forward.

      Screenshot KVM VM Create Select ISO

  5. Under Choose memory and CPU settings:

    1. Set the amount of memory available to the VM. The minimum is 2048 MB, however 4096 MB is suggested.

    2. Optionally, set the number of CPUs available to the VM.

    3. Click Forward.

      Screenshot KVM VM Create Memory and CPU

  6. On the next dialog you will specify the virtual hard disk (VHD) size. The size of the VHD, should be a minimum of 20 GB. While this setting can be changed later, it is a multi-step process not covered by this guide. Therefore it is recommended that you size the VHD to be large enough for your software development activities.

    1. Check Enable storage for this virtual machine.

    2. Check Create a disk image for the virtual machine.

    3. Set the desired VHD size.

    4. Click Forward.

      Screenshot KVM VM Create VHD size

  7. Under Ready to begin the installation:

    1. Set the Name to rhel.

    2. Click Finish.

The newly created VM will now boot up from the .iso file to start the installation.

Install Red Hat Enterprise Linux

This section provides a brief overview of the steps for installing Red Hat Enterprise Linux. Detailed instructions can be found in the Red Hat Enterprise Linux Installation Guide.

There are a few key steps to remember during the installation process:

  1. The Installation destination will be the virtual hard disk you created for the VM.

  2. You should configure networking under Network and host name before starting the installation. You will need access to the Internet to complete registration and download additional software. The network can be configured after the system is installed. However, the steps are more straightforward during installation.

  3. Select Server with a GUI under Software Selection so the system will boot into the full graphical environment after installation. By default, Red Hat Enterprise Linux Server will not install a graphical desktop.

  4. Create your primary user account during installation: After the installation begins, you will be instructed to set a password for the root account and be given the opportunity to create a regular user account. You should create a user before the installation process completes. The regular user will be your primary login for development. The root account should only be used for system administration tasks. If you don’t create a user before the installation completes, you will need to reboot and then log in as root to create user accounts.

Install the latest updates

In this step, you will download and install the latest updates for your system from Red Hat. In the process, you will verify that your system has a current Red Hat subscription and is able to receive updates.

First, start a Terminal window from the Application menu. Then, after using su to change to the root user ID, use subscription-manager to verify that you have access to Red Hat software repositories.

$ su -
# subscription-manager repos --list-enabled

If you don’t see any enabled repositories, your system might not be registered with Red Hat or might not have a valid subscription. See Troubleshooting and FAQ for more information.

Now download and install any available updates by running yum update.

# yum -y update

If yum updates the kernel package or installs a large number of updates, you should reboot your system. You can do this from the VM’s desktop by clicking the down arrow icon in the upper right corner, then clicking the power icon. Alternatively you can reboot the system from the command line:

# reboot

Enable additional software repositories

In this step you will configure your system to obtain software from the Optional RPMs and RHSCL software repositories. The Optional RPMs repository includes a number of development packages. The RHSCL repository includes the both the RHSCL software collections as well as DTS (the Red Hat Developer Toolset).

# subscription-manager repos --enable rhel-server-rhscl-7-rpms
# subscription-manager repos --enable rhel-7-server-optional-rpms

KVM/libvirt Networking

The default network configuration is for the VM to share the host system’s network connection(s) and IP address using network address translation (NAT). This is the easiest to manage and will be fine for many uses. Using NAT, the VM will be able to access resources on your network or the Internet. However services, such as a web server, running inside the VM won’t be directly accessible from outside of the VM.

Alternatively, you can attach the VM to directly network by sharing the network adapter from the host system as a bridged network adapter. In this configuration, the VM gets its own IP address, usually using your network’s DHCP server. The VM appears on the network the same way a physical computer would with its own hardware MAC address. The host’s network adapter is shared by creating a network bridge. The VM’s virtual network adapter can only be bridged to one physical network adapter at a time. If your system has more than one network adapter you need to choose which one to attach to. If your system switches between wired and wireless connections, you will need to switch bridged adapters for the VM.

Networking, both physical and virtual, is a large topic beyond the scope of this guide. For more information see your system’s documentation.

This step provides an overview of the key steps for installing Red Hat Enterprise Linux Server in a VirtualBox Virtual Machine (VM) so you can get started with software development. The VM you create will give you a Red Hat Enterprise Linux development environment that you can use on your system running Microsoft Windows, Mac OS X, Ubuntu, or other Linux.

Overview of steps

  1. Download and install VirtualBox.

  2. Configure a VM to run Red Hat Enterprise Linux.

  3. Boot the VM using the ISO file you downloaded in step 1 as a virtual DVD.

  4. Install Red Hat Enterprise Linux.

Note: This tutorial does not replace the Red Hat Enterprise Linux Installation Guide or VirtualBox User Manual. Instead, this tutorial provides an overview of the key steps for software developers. For detailed instructions, see the respective manual.

A few things to keep in mind:

  • You will be using the Server edition of Red Hat Enterprise Linux. This provides you with the widest range of software to develop and test with.

  • The VM will have a full graphical desktop. You will select Server with a GUI during installation.

  • After installation, you will configure additional software repositories that will provide you access to optional development software such as RHSCL and DTS.

System Requirements

The requirements for your physical system that will host the Red Hat Enterprise Linux VM are:

  • a 64-bit x86 machine with hardware virtualization assistance (Intel VT-X or AMD-V).

  • An operating system supported by VirtualBox such as Microsoft Windows 7 or later, Apple Mac OS X 10.8 or later, Ubuntu Linux 12.04 or later.

  • 4 GB RAM (8 GB preferred).

  • 24 GB of available disk space for the VM, the installation ISO file, and VirtualBox.

If you encounter difficulties at any point in this tutorial, see Troubleshooting and FAQ.

Download and install VirtualBox

This guide uses VirtualBox is 5.0.x. You may also use VirtualBox 4.3.x though there will be some minor differences from what is described here. Older versions of VirtualBox may work but have not been tested.

Microsoft Windows or Apple Mac OS X

Go to the VirtualBox Download page and download the installer for your system. After the download completes, click on the downloaded .exe or .dmg file to start the installation. During the installation you will need to agree to using administrative privileges for a number of the steps.

Ubuntu Linux and other Linux systems

Ubuntu Linux and other Linux distributions includes packages for VirtualBox that you can install using your regular package management commands. On Ubuntu Linux use the following command:

$ sudo apt-get install virtualbox

If your distribution doesn’t include VirtualBox packages or the packages are older than VirtualBox 4.3.x, see the VirtualBox for Linux download page to download a package for your system.

Optional step: Install VirtualBox Extension Pack

A extension package is available for VirtualBox that provides support for USB devices, remote desktop access via RDP, and PXE boot. The software is provided in binary form as it is not open-source. The extension package is available on the VirtualBox Download page.

Enable Intel VT-x or AMD-V Virtualization in BIOS/UEFI

Intel and AMD processors have hardware extensions for accelerating virtualization. On some systems this support may be disabled by default in the system’s BIOS/UEFI. To enable the extensions, you might have to go into the system’s BIOS/UEFI setup configuration at boot time. Consult your system’s hardware documentation for more information.

Disable Microsoft Hyper-V to avoid conflicts with VirtualBox

On some Microsoft Windows systems it may be necessary to disable Microsoft Hyper-V virtualization in order to use VirtualBox. Only one virtualization platform, or hypervisor, can be active on a host system at a time. While hypervisors like VirtualBox only take control of the host system’s hardware virtualization capabilities when they are actually running a VM, Microsoft Hyper-V takes control at boot time. In order to use VirtualBox, Hyper-V must either be disabled or uninstalled. Consult Microsoft’s documentation for more information. Note: if you are interested in using Microsoft Hyper-V instead of VirtualBox, follow the steps in the Hyper-V tab at the top of this page.

Create and configure a VM in VirtualBox

In this step you will create and configure the VM that will run Red Hat Enterprise Linux. The system you are running VirtualBox on is called the host system. Note: VirtualBox refers to the VM running Red Hat Enterprise Linux as the guest system. However, most of the options to control the VM are under the Machine menu entry.

First, launch VirtualBox from your system’s menu. On some systems, the menu entry will be called Oracle VM VirtualBox.

Before you create any VMs, you may wish to change where VirtualBox stores the files that are used as virtual hard disks for the VMs you create. By default, VirtualBox places these files in your home directory. You will need at least 20 GB of available space. To change the location, select Preferences from the File menu. Under General, change Default Machine Folder to your preferred location.

Click the New button to create a new VM. A series of dialog boxes will come up for you to configure the VM:

  1. On the Create Virtual Machine dialog:

    1. Enter RHEL as the name or part of the name. This will be the name of the created VM in VirtualBox. Including RHEL will automatically set VM Type and Version.

    2. Ensure that Type is set to Linux and Version is set to Red Hat (64-bit).

    3. Click Next.

      Screenshot VirtualBox VM Create

  2. Set the VM memory size to at least 2048 MB on the Memory size dialog. This value can be changed later. The minimum you should use is 2048 MB, however 4096 MB is suggested. Then, click Next.

  3. Next you will configure the new VM’s virtual hard disk. The size of the virtual hard disk, should be a minimum of 20 GB. While this setting can be changed later, it is a multi-step process not covered by this guide. Therefore it is recommended that you size the virtual hard disk to be large enough for your software development activities. Note: The space on your host system’s physical disk will not be allocated until it is used by the VM. Complete the next set of dialog boxes to configure the virtual hard disk:

    1. Select Create a virtual hard disk now on the Hard disk dialog. Then, click Create to move to the next dialog.

    2. Select VDI (VirtualBox Disk Image) on the Hard disk file type dialog. Then, click Next.

    3. Select Dynamically allocated on the Storage on physical hard disk dialog. Then, click Next.

      Screenshot HD Dynamic

    4. On the File location and size dialog:

      1. Change the name and location if desired.

      2. Set the size to be a minimum of 20 GB.

      3. Click Create.

        Screenshot File Location

At this point the basic VM has been created, however additional configuration is necessary. Click to select the new VM so that it is highlighted, then click the Settings button. Make the following changes:

Screenshot VM Created

  1. Select the General group, then click the Advanced tab. Enable copy-and-paste between the host system and the VM by setting Shared Clipboard and Drag’n’Drop to Bidirectional. Note: copy-and-paste will only be available after VirtualBox Guest Additions are installed on the VM during step 3.

    Screenshot Settings Advanced

  2. By default, the VM will have a single virtual processor. If your system has multiple processors or cores, you can add more. Select the System group, then click the Processor tab. Adjust Processors to the desired value.

    Screenshot Settings Processor

  3. In the Network group, under the Adapter 1 tab, you can configure the VM’s networking configuration. The default is Network Address Translation (NAT) which is recommended because it is the easiest to manage. You may want to choose Bridged to attach the VM directly to the physical network. See VirtualBox Networking below for more information.

  4. Next, configure the VM to use the Red Hat Enterprise Linux Server binary DVD ISO file as a virtual CD/DVD:

    1. Select the Storage section of the VM Settings dialog.

    2. Under Controller: IDE, select the CD icon that says Empty next to it.

    3. On the right side, under Attributes, click the CD icon on the far right.

    4. Select Choose Virtual Optical Disk File.

    5. Navigate to the Red Hat Enterprise Linux Server binary DVD ISO file that you downloaded earlier.

  5. Click OK to close the VM settings dialog.

    Screenshot Settings RHEL DVD

Create a shared folder between the host system and the VM (Optional)

You may create a folder that is shared between your host system and the Red Hat Enterprise Linux VM. This makes it easy to share files such as source code between the two systems. The configuration for shared folders can be performed now or anytime later.

Shared folders will only be available on the VM after the VirtualBox Guest Additions software is installed on the VM. Installation of VirtualBox Guest Additions is covered in step 3 with the other Red Hat Enterprise Linux post-installation steps.

To add a shared folder:

  1. Select your RHEL VM in VirtualBox, the click the Settings button.

  2. Select the Shared Folders group.

  3. Click the folder icon with a + in the upper right corner.

  4. In the Add Share dialog:

    1. Enter the path on the host system in the Folder Path.

    2. Enter a name without spaces for the shared folder on the VM.

  5. Click OK to close the VM Settings dialog.

    Screenshot VirtualBox Shared Folder

The path to shared folders on the VM will be /media/sf_<foldername>.

Boot the VM and install Red Hat Enterprise Linux

This section provides a brief overview of the steps for installing Red Hat Enterprise Linux. Detailed instructions can be found in the Red Hat Enterprise Linux Installation Guide.

There are a few key steps to remember during the installation process:

  1. The Installation destination will be the virtual hard disk you created for the VM.

  2. You should configure networking under Network and host name before starting the installation. You will need access to the Internet to complete registration and download additional software. The network can be configured after the system is installed. However, the steps are more straightforward during installation.

  3. Select Server with a GUI under Software Selection so the system will boot into the full graphical environment after installation. By default, Red Hat Enterprise Linux Server will not install a graphical desktop.

  4. Create your primary user account during installation: After the installation begins, you will be instructed to set a password for the root account and be given the opportunity to create a regular user account. You should create a user before the installation process completes. The regular user will be your primary login for development. The root account should only be used for system administration tasks. If you don’t create a user before the installation completes, you will need to reboot and then log in as root to create user accounts.

Installation instructions

A few notes about working with VirtualBox:

  • When you click inside the VM window, the mouse pointer and keyboard will be captured by the VM until you release them by hitting the Host Key. The lower right corner of the VirtualBox window shows which key is the Host Key for your OS. On Windows and Linux it is the right Ctrl key. On Mac OS is it the left Command (⌘) key.

  • After you install VirtualBox Guest Additions, the integration the of mouse pointer will be improved. You will no longer need to hit the Host Key to move the focus outside of the VM window.

  • VirtualBox will display some pop-up messages in the VM window. You can dismiss those after to reading them. Note: you won’t be able to click on the pop-up messages if your mouse pointer is captured by the VM. Hit the Host Key to release the pointer, then click to dismiss the pop-up boxes.

  • For more information see Chapter 1. First steps in the VirtualBox User Manual.

  8. Finally, Click the ‘X’ in the upper right hand corner to close the Settings application.

Install the latest updates

In this step, you will download and install the latest updates for your system from Red Hat. In the process, you will verify that your system has a current Red Hat subscription and is able to receive updates.

First, start a Terminal window from the Application menu. Then, after using su to change to the root user ID, use subscription-manager to verify that you have access to Red Hat software repositories.

$ su -
# subscription-manager repos --list-enabled

If you don’t see any enabled repositories, your system might not be registered with Red Hat or might not have a valid subscription. See Troubleshooting and FAQ for more information.

Now download and install any available updates by running yum update.

# yum -y update

If yum updates the kernel package or installs a large number of updates, you should reboot your system. You can do this from the VM’s desktop by clicking the down arrow icon in the upper right corner, then clicking the power icon. Alternatively you can reboot the system from the command line:

# reboot

Enable additional software repositories

In this step you will configure your system to obtain software from the Optional RPMs and RHSCL software repositories. The Optional RPMs repository includes a number of development packages. The RHSCL repository includes the both the RHSCL software collections as well as DTS (the Red Hat Developer Toolset).

# subscription-manager repos --enable rhel-server-rhscl-7-rpms
# subscription-manager repos --enable rhel-7-server-optional-rpms

Install VirtualBox Guest Additions

Enhanced VM integration is available by installing VirtualBox Guest Additions on the Red Hat Enterprise Linux VM. The enhancements include:

  • Better mouse pointer integration that eliminates the need to capture the pointer within the VM.

  • Copy and paste between the VM and the host system.

  • Folders that are shared from the host system to the VM. This can be helpful for making your source code available on the VM.

  • Ability to dynamically resize the VM’s window which will change the size of the graphical desktop inside the VM.

VirtualBox Guest Additions are packaged as a .iso file, which will be used on the VM as a virtual CD. VirtualBox will load the virtual CD when you select Insert Guest Additions CD image from the menu. To install VirtualBox Guest Editions:

  • You need to be logged into Red Hat Enterprise Linux with the graphical desktop running.

  • You need to have installed Development Tools during installation. The development tools are used to compile the VirtualBox drivers.

The steps to install VirtualBox Guest Additions are:

  1. Select Insert Guest Additions CD image from the Devices menu of the VM window.

  2. A dialog box will pop up asking you if you want to run the software on the virtual CD. Click Run.

    Screenshot VirtualBox Guest Additions Auto Run

  3. Enter the password for the root user when prompted. Then click Authenticate.

    Screenshot VirtualBox Root Password Prompt

  4. Terminal window will appear with the install process running inside of it. When the process it complete you will be prompted to hit Return to close the window.

    Screenshot VirtualBox Guest Addition Install Complete

  5. Eject the virtual CD by right clicking on its icon on the desktop and selecting Eject.

Note: If you upgrade VirtualBox on your host system, you will need to repeat these steps.

VirtualBox Networking

The default VirtualBox network configuration is for the VM to share the host system’s network connection(s) and IP address using network address translation (NAT). This is the easiest to manage and will be fine for many uses. Using NAT, the VM will be able to access resources on your network or the Internet. However services, such as a web server, running inside the VM won’t be directly accessible from outside of the VM.

You can make specific services on the VM accessible using port forwarding. For example you can configure port forwarding so that port 8080 on your host system maps to port 80 on the VM.

Alternatively, you can attach the VM to directly network by sharing the network adapter from the host system as a bridged network adapter. In this configuration, the VM gets its own IP address, usually using your network’s DHCP server. The VM appears on the network the same way a physical computer would with its own hardware MAC address. The host’s network adapter is shared by a device driver that is installed by VirtualBox. The VM’s virtual network adapter can only be bridged to one physical network adapter at a time. If your system has more than one network adapter you need to choose which one to attach to. If your system switches between wired and wireless connections, you will need to switch bridged adapters for the VM.

Networking, both physical and virtual, is a large topic beyond the scope of this guide. For more information see Virtual Networking in the VirtualBox User Manual.

Body

This step provides an overview of the key steps for installing Red Hat Enterprise Linux Server in a VMware Virtual Machine (VM) so you can get started with software development. The VM you create will give you a Red Hat Enterprise Linux development environment that you can use on your system running Microsoft Windows or Mac OS X.

Overview of steps

  1. Download and install VMware

  2. Configure a VM to run Red Hat Enterprise Linux.

  3. Boot the VM using the ISO file you downloaded in step 1 as a virtual DVD.

  4. Install Red Hat Enterprise Linux.

Note: This tutorial does not replace the Red Hat Enterprise Linux Installation Guide or VMware documentation. Instead, this tutorial provides an overview of the key steps for software developers. For detailed instructions, see the respective manual.

A few things to keep in mind:

  • You will be using the Server edition of Red Hat Enterprise Linux. This provides you with the widest range of software to develop and test with.

  • The VM will have a full graphical desktop. You will select Server with a GUI during installation.

  • After installation, you will configure additional software repositories that will provide you access to optional development software such as RHSCL and DTS.

System Requirements

The requirements for your physical system that will host the Red Hat Enterprise Linux VM are:

  • a 64-bit x86 machine with hardware virtualization assistance (Intel VT-X or AMD-V).

  • 4 GB RAM (8 GB preferred).

  • 24 GB of available disk space for the VM, the installation ISO file, and VMware.

If you encounter difficulties at any point in this tutorial, see Troubleshooting and FAQ.

Download and install VMware.

You will need to download a VMware desktop virtualization product for your system:

After the download completes, click on the downloaded .exe or .dmg file to start the installation. During the installation you will need to agree to using administrative privileges for a number of the steps.

The Windows enhanced virtual keyboard driver is not required. You may install it if needed for improved support of international keyboards.

Note: This guide uses VMware Workstation 12 and VMware Fusion 8. Older versions may work but the steps might be slightly different.

Enable Intel VT-x or AMD-V Virtualization in BIOS/UEFI

Intel and AMD processors have hardware extensions for accelerating virtualization. On some systems this support may be disabled by default in the system’s BIOS/UEFI. To enable the extensions, you might have to go into the system’s BIOS/UEFI setup configuration at boot time. Consult your system’s hardware documentation for more information.

Disable Microsoft Hyper-V to avoid conflicts with VMware

On some Microsoft Windows systems it may be necessary to disable Microsoft Hyper-V virtualization in order to use VMware. Only one virtualization platform, or hypervisor, can be active on a host system at a time. While hypervisors like VMware only take control of the host system’s hardware virtualization capabilities when they are actually running a VM, Microsoft Hyper-V takes control at boot time. In order to use VMware, Hyper-V must either be disabled or uninstalled. Consult Microsoft’s documentation for more information. Note: if you are interested in using Microsoft Hyper-V instead of VMware, follow the steps in the Hyper-V tab at the top of this page.

Create and configure a VM in VMware

In this step you will create and configure the VM that will run Red Hat Enterprise Linux. The system you are running VMware on is called the host system. The operating system running inside the VM is referred to as the guest.

First, launch VMware from your system’s menu. The follow the steps for your operating system.

Boot the VM and install Red Hat Enterprise Linux

To start the VM and begin installation:

  1. Start VMware if it isn’t already running

  2. select the rhel VM.

  3. click the Play button.

The VM should now boot up from the Red Hat Enterprise Linux Server DVD .iso file.

Note: When you click inside the VM window, the keyboard and mouse will be captured by the VM until you hit Ctrl and Alt on Windows or Ctrl and the Command key (⌘) on the Mac. When the system is fully installed this will no longer be necessary. See Open VM Tools replaces VMware Tools for Linux.

This section provides a brief overview of the steps for installing Red Hat Enterprise Linux. Detailed instructions can be found in the Red Hat Enterprise Linux Installation Guide.

There are a few key steps to remember during the installation process:

  1. The Installation destination will be the virtual hard disk you created for the VM.

  2. You should configure networking under Network and host name before starting the installation. You will need access to the Internet to complete registration and download additional software. The network can be configured after the system is installed. However, the steps are more straightforward during installation.

  3. Select Server with a GUI under Software Selection so the system will boot into the full graphical environment after installation. By default, Red Hat Enterprise Linux Server will not install a graphical desktop.

  4. Create your primary user account during installation: After the installation begins, you will be instructed to set a password for the root account and be given the opportunity to create a regular user account. You should create a user before the installation process completes. The regular user will be your primary login for development. The root account should only be used for system administration tasks. If you don’t create a user before the installation completes, you will need to reboot and then log in as root to create user accounts.

Disable lock screen and screen power saving

For security and to save energy, the default configuration of Red Hat Enterprise Linux is to lock the screen and turn the screen off when idle. On a VM, it is best to disable these features since the host system will control screen locking and power saving.

To disable these features, from the desktop Application menu, select the System Tools group, then select Settings. Follow these steps in the Settings application.

  1. Click the Privacy icon to bring up the Privacy dialog.

  8. Finally, Click the ‘X’ in the upper right hand corner to close the Settings application.

Install the latest updates

In this step, you will download and install the latest updates for your system from Red Hat. In the process, you will verify that your system has a current Red Hat subscription and is able to receive updates.

First, start a Terminal window from the Application menu. Then, after using su to change to the root user ID, use subscription-manager to verify that you have access to Red Hat software repositories.

$ su -
# subscription-manager repos --list-enabled

If you don’t see any enabled repositories, your system might not be registered with Red Hat or might not have a valid subscription. See Troubleshooting and FAQ for more information.

Now download and install any available updates by running yum update.

# yum -y update

If yum updates the kernel package or installs a large number of updates, you should reboot your system. You can do this from the VM’s desktop by clicking the down arrow icon in the upper right corner, then clicking the power icon. Alternatively you can reboot the system from the command line:

# reboot

Enable additional software repositories

In this step you will configure your system to obtain software from the Optional RPMs and RHSCL software repositories. The Optional RPMs repository includes a number of development packages. The RHSCL repository includes the both the RHSCL software collections as well as DTS (the Red Hat Developer Toolset).

# subscription-manager repos --enable rhel-server-rhscl-7-rpms
# subscription-manager repos --enable rhel-7-server-optional-rpms

Finally, reboot the VM. You can do this from the VM’s desktop by clicking the down arrow icon in the upper right corner, then clicking the power icon. Alternatively you can reboot the system from the command line:

# reboot

VMware Networking

The default VMware network configuration is for the VM to share the host system’s network connection(s) and IP address using network address translation (NAT). This is the easiest to manage and will be fine for many uses. Using NAT, the VM will be able to access resources on your network or the Internet. However services, such as a web server, running inside the VM won’t be directly accessible from outside of the VM.

Alternatively, you can attach the VM to directly network by sharing the network adapter from the host system as a bridged network adapter. In this configuration, the VM gets its own IP address, usually using your network’s DHCP server. The VM appears on the network the same way a physical computer would with its own hardware MAC address. The host’s network adapter is shared by a device driver that is installed by VMware. The VM’s virtual network adapter can only be bridged to one physical network adapter at a time. If your system has more than one network adapter you need to choose which one to attach to. If your system switches between wired and wireless connections, you will need to switch bridged adapters for the VM.

Networking, both physical and virtual, is a large topic beyond the scope of this guide. For more information see Networking options in VMware Workstation and Fusion or the networking section of the VMware Workstation User’s Guide.

Open VM Tools replaces VMware Tools for Linux

Red Hat Enterprise Linux includes Open VM Tools which replaces the VMware’s Operating System Specific Tools (OST), also known as VMware Tools for Linux. You do not need to install VMware Tools as the functionality is implemented in the open source packages that are included with Red Hat Enterprise Linux. These tools are services and drivers that are installed in the guest operating system under the VM to:

  • Enable copy-and-paste between the host system and the VM.

  • Provide better mouse pointer integration.

  • Allow resizing of the VM window which will change the size of VM’s graphical desktop.

  • Improve VM performance.

Open VM Tools does not currently include the driver that is needed for shared folders. To enable shared folders you need to run the VMware Tools installer.

Enable VMware shared folders

You may create a folder that is shared between your host system and the Red Hat Enterprise Linux VM. This makes it easy to share files such as source code between the two systems. Enabling VMware shared folders requires installing the VMware Host Guest File System (VMHGFS) driver on the VM. The VMHGFS driver is included with VMware Tools. By default, the VMware Tools installer will install the VMHGFS driver and leave the existing installation of Open VM Tools intact. This is the suggested configuration for enabling shared folders.

To install VMHGFS:

  1. VMware Tools are packaged as a .iso file, which will be used on the VM as a virtual CD. VMware will load the virtual CD when you select Install VMware Tools.

    For VMware Player on Windows, select Manage from the Player menu. Then select Install VMware Tools.

    For VMware Fusion on Mac OS, select Install VMware Tools from the Virtual Machine menu. Then click Install on the pop-up.

  2. Dismiss the Open with Files pop-up on the VM by clicking the X.

  3. If VMware adds a message at the bottom of the VM window, dismiss it by clicking on the X.

  4. Open a Terminal window in the VM from the Applications menu.

  5. Change to the root user with su -. You will need to enter the root password.

  6. Enter the following commands:

# mkdir /mnt/cd
# mount -o ro /dev/sr0 /mnt/cd
# cd /tmp
# mkdir vmware-tools
# cd vmware-tools
# ls /mnt/cd/*.tar.gz

In the directory listing, make a note of the exact file name of the .tar.gz file to use in the next command as the version number may have changed.

# tar xvzf /mnt/cd/VMwareTools-10.0.5-3228253.tar.gz

Enter the follow command to start the VMware Tools installer:

# cd vmware-tools-distrib
# ./vmware-install.pl

The installer will ask a series of questions. Accept all the default choices by hitting the return key with the exception of Would you like to enable VMware automatic kernel modules?. Answer yes to enable automatic kernel modules.

When the installer is finished, eject the virtual CD:

# eject

Create a shared folder mapping (Microsoft Windows)

  1. From the Player menu, select Manage, then select Virtual Machine Settings.

  2. Select the Options tab on the left from the VM Settings dialog.

  3. Select Shared Folders in the list on the left.

  4. Select Always Enabled under Folder Sharing on the right.

  5. Click the Add button.

  6. On the Add Shared Folder Wizard, click Next.

  7. Click Browse and navigate to the folder you wish to share.

  8. Enter the name for the shared folder on VM. Do not use spaces.

  9. Click Next.

  10. On the _Specify Shared Folder Attributes:

    1. Make sure Enable this share is checked.

    2. Optionally, check Read-only if you want to prevent the VM from being able to modify the shared folder.

    3. Click Finish.

  11. Click OK to close the Virtual Machine Settings dialog.

On the VM the path to the shared folders will be /mnt/hgfs/<folder name>.

Create a shared folder mapping (Mac OS X)

  1. Click the Settings (Wrench icon) button.

  2. Click the Sharing icon under System Settings.

  3. On the Sharing dialog:

    1. Make sure Enabled Shared Folders is checked.

    2. Click the + button.

    3. Navigate to the folder you wish to share.

    4. Click Add.

  4. Optionally, change the name of the shared folder by clicking in the Name column. Do not use spaces in the name.

  5. If you want to prevent the VM from modifying the folder, select Read Only in the Permissions column.

  6. Close the Sharing dialog.
