Does it work if you supply xauth= and display= properties? See http://libvirt.org/formatdomain.html#elementsGraphics
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Matt? See also bug #536693
I no longer get the AVC with or without xauth and display, so I'm happy to close this bug. It still doesn't work, though, so I added a comment to the bug you referenced.
Closing as WORKSFORME per comment #4
