Announcing the Red Hat Advanced Cluster Management 2.16 general availability (GA) of namespace and virtualization right-sizing recommendations.

Learn how to quickly provision and configure customized test VMs using Kickstart together with features of the standard Linux virtualization stack (libvirt + Qemu + KVM) and Red Hat Enterprise Linux. This article demonstrates a simple set of scripts that can be stored in a Git repository, useful for developers not running Linux desktops. Windows users can take advantage of these scripts on any distribution that supports Windows Subsystem for Linux (WSL2), creating a Red Hat Enterprise Linux VM inside the WSL VM. MacOS users can also use these scripts with rootless VMs.
