Migrating VMs

The migration toolkit for virtualization (MTV), included in all OpenShift editions, migrates VMs at scale to Red Hat OpenShift Virtualization and only requires a few simple steps. MTV supports both cold and warm migrations. MTV currently supports multiple platforms.

MTV can support live migrations between nodes running on OpenShift. Live migration moves a running VM to a different node in a cluster without disrupting the workload. There are two types of migrations, cold and warm. Warm migration is done on an active and running VM. During warm migrations, data is copied during a pre-copy stage while the source VM is still running. The VM is then shut down and the balance of the data is copied during the cutover stage. During cold migrations, the VM at the original host is shut down while data is copied.

For migrating hundreds or more VMs to OpenShift Virtualization, Red Hat Ansible Automation Platform and MTV can be combined.

Demystifying Networking

OpenShift Virtualization can use OpenVirtual Network (OVN)-Kubernetes, OpenShift Software Defined Network, or other certified network plug-ins. Container network interfaces (CNIs) provide a pluggable interface to configure network interfaces in containers. Multus CNIs are CNI plug-ins that can run other CNI plug-ins. OpenShift uses Multus to attach multiple network interfaces to pods. A software bridge is a link layer device that behaves like a network switch, sending packets between interfaces that are connected to it. A bridge on a RHEL host emulates a hardware bridge or in virtual environments, integrates VMs to the same network as the host.

What about storage?

OpenShift supports multiple types of storage for on-premise and cloud providers. Container storage for persistent and non-persistent data can be managed in OpenShift. OpenShift Virtualization uses persistent volumes (PVs) with shared storage across worker nodes which are linked as persistent volume claims (PVCs). Pvs let cluster administrators provision persistent storage for a cluster. With PVCs, developers can request access to PVs without working about the underlying storage infrastructure.

Multi-cluster Hosting

OpenShift Virtualization supports cross-cluster management with Red Hat Advanced Cluster Management for Kubernetes (RHACM). RHACM manages the fleet which provides multi-cluster management, cross-cluster observability and cross-cluster resource searching for admins.

OpenShift Virtualization supports the use of disaster recovery (DR) to make sure that an environment can recover for an outage. Two methods are supported, metropolitan disaster recovery (Metro-DR) and regional-DR. Metro-DR leverages synchronous replication which writes to storage on both the primary and secondary sites so that the data is synchronized between sites. Regional-DR uses asynchronous replication where data from the primary site is synchronized with the secondary site at regular intervals. The choice of DR is determined by latency and throughput requirements. OpenShift GitOps manages the application and Red Hat Advanced Cluster Management running on the hub cluster orchestrates the failover.

OpenShift Virtualization also supports the use OpenShift Data Foundation Metro-DR solution or OpenShift Data Foundation Regional-DR. Red Hat Advanced Cluster Management allows the management of multiple OpenShift clusters including deployed applications and is needed for both OpenShift Data Foundation Disaster Recovery solutions.

Self-service VMs

Platform engineers or admins can create VM templates which are preconfigured VM images that include an OS, applications, and configuration required to deploy new VMs. VM templates ensure that all VMs are standardized, can be quickly deployed, are identical, allow for rapid scaling of virtual environments, and makes management and maintenance of the virtual environments easier.

These templates can used by developers to create multiple identical VMs that can be requested as needed. Once created, these VM templates can be used for disaster recovery, development and testing, production environments, etc.

Red Hat OpenShift Virtualization Engine

Red Hat OpenShift Virtualization Engine is an edition of Red Hat OpenShift and made for hosting and running virtual machines. It is optimized for bare metal operating in a limited space and supports 128 cores per bare-metal socket pair. OpenShift Virtualization Engine is deployed and managed using the same tools and processes for other editions of OpenShift on bare metal deployments, including using the assisted installer, agent-based installer, installer provisioned infrastructure, and user provisioned infrastructure methods for deploying bare metal clusters and the familiar set of Operators for adding cluster functionality.
