20.3 Preparing RHEL 8 for KVM Virtualization
Unlike Xen, it is not necessary to run a special version of the kernel in order to support KVM. As a result KVM support is already available for use with the standard kernel via the installation of a KVM kernel module, thereby negating the need to install and boot from a special kernel.
To avoid conflicts, however, if a Xen enabled kernel is currently running on the system, reboot the system and select a non-Xen kernel from the boot menu before proceeding with the remainder of this chapter.
The tools required to setup and maintain a KVM-based virtualized system are not installed by default unless specifically selected during the RHEL 8 operating system installation process. To install KVM from the command prompt, execute the following command in a terminal window:
# dnf install qemu-kvm qemu-img libvirt virt-install libvirt-client
If you have access to a graphical desktop environment the virt-manager package is also recommended...
