=head1 NAME
virt-host-validate - validate host virtualization setup
=head1 SYNOPSIS
virt-host-validate [OPTIONS...] [HV-TYPE]
=head1 DESCRIPTION
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
=head1 OPTIONS
=over 4
=item C<-v>, C<--version>
Display the command version
=item C<-h>, C<--help>
Display the command line help
=item C<-q>, C<--quiet>
Don't display details of individual checks being performed.
Only display output if a check does not pass.
=back
=head1 EXIT STATUS
Upon successful validation, an exit status of 0 will be set. Upon
failure a non-zero status will be set.
