This tool validates that the host is configured in a suitable way to run libvirt hypervisor drivers. If invoked without any arguments it will check support for all hypervisor drivers it is aware of. Optionally it can be given a particular hypervisor type ('qemu' or 'lxc') to restrict the checks to those relevant for that virtualization technology.
