I think this is a dupe that's been fixed in Satellite 5.1. We had code go out in
5.0 that worked at the time but later broke with updates to libvirt in RHEL 5.1
causing this hung xenconsole process. The unpredictable code was removed in Sat
5.1 in favor of something much more consistently reliable.
