[libvirt] [PATCH 1/3] Ensure failure to talk to Xen hypervisor is fatal when privileged

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berra...@redhat.com>

As per the comment, the Xen hypervisor driver is considered to
be mandatory when running privileged. When it fails to open,
we should thus return an error, not ignore it.
