Hi,I am trying to start a fully virtualized guest called "full1" remotely. The connection URI I am using is "xen+ssh://root@dell1/". (Note that I am able to start/stop/resume/shutdown para-virtualized guests without any problems with this connection URI.)The XML definition for the fully virtualized guest is this: <domain

I think this is an instance of bug: https://bugzilla.redhat.com/show_bug.cgi?id=279581
Can you try the patch in that bug please (it fixed the problem for me).
