Comment 3 Cole Robinson 2010-06-25 12:42:22 EDT
Can you provide 

virsh dumpxml $vmname

Reassigning to libvirt
Comment 4 Daniel Berrange 2010-06-28 12:05:39 EDT
This error normally occurs because someone has modified the system cgroups configuration after libvirtd had started. Can you restart libvirtd and see if the problem goes away.
Comment 5 Daniel Veillard 2010-07-15 11:28:27 EDT
No feedback, and possibly an user error on a problem we can't reproduce,
so closing it unless this can be reproduced again, in which case reopen
and provide the informations being asked.
