libvirt

Install and configure libvirt on Fedora.

This role allows users to run virtual machines in userspace. It also configures Kernel same-page Merging (KSM).

Requirements

Your computer must have enough hardware resources to support running virtual machines. You might also have to enable virtualization in your computer's BIOS.
