[Libvirt-cim] [PATCH 1 of 2] RPCC: returns instances of Xen on a KVM only system

# HG changeset patch # User Heidi Eckhart <heidieck(a)linux.vnet.ibm.com&gt; # Date 1201865505 -3600 # Node ID d4b86a39d55d2208c5f56a6666ccc212ab60a240 # Parent 6b1bf8231d82f51f25ac3d954b63962bfc7484c9 RPCC: returns instances of Xen on a KVM only system This breaks the approach that is used all over libvirt-cim providers, where only instances of the currently supported hypervisor type are returned.
