libvirt/relax-qemu-usergroup-check.patch

Allow qemu driver (and hence libvirtd) to load when qemu
user:group does not exist.  The kvm package, which may not
exist on a xen host, creates qemu user:group.

A better (future) solution would be to build the libvirtd
drivers as loadable modules instead of built-in to the
daemon.  Then the qemu driver would only be loaded when needed,
which would never be the case on a xen-only configuration.
