Often this is because libvirtd crashed.  After this command, check that libvirtd
is still running, and if not, you might want to collect the core dump from it
and get the output of "thread apply all bt".

At this point, though, this is an ancient libvirt.  I would suggest at least
upgrading to the RHEL-5.4 version of libvirt, and see if you can reproduce the
issue.  If you can, then I would try again with the recently released 0.7.1, and
if you are still having problems, then collect the information like I mentioned
above.
