[libvirt] [PATCH] Fixing issues in re-detection of transient VMs

Re-detection of transient VMs had two issues described in bugs 507304 and 507537: https://bugzilla.redhat.com/show_bug.cgi?id=507304 Summary: After a migration the domain status is saved as "paused" and it is not updated to "running". A following libvirtd restart will detect the vm as "paused" (instead of "running"). https://bugzilla.redhat.com/show_bug.cgi?id=507537 Summary: Destroying a transient re-detected domain leaves the domain defined (instead of completely remove it). Patches in attachment (and available in the bug report). -- Federico Simoncelli.
