In Xen <= 3.0.x inactive domain configs are not managed by XenD at
all, so libvirt has some hacky code to read files in /etc/xen. In
Xen >= 3.1.0 XenD has proper management APIs for inactive guests and
libvirt uses that instead.

So if you upgrade from 3.0.x to > 3.1.x then any config files in
/etc/xen should be loaded into XenD using 'xm new CONFIG'. libvirt
will then be able to see & manage them properly
