Comment 4 Dave Allan 2011-12-19 21:28:03 UTC 
Is this behavior reproducible on the current 6.3 builds?
Comment 5 Nan Zhang 2011-12-21 06:41:39 UTC 
Yes, it's also reproducible on libvirt-0.9.8-1.el6.x86_64 build.

Comment 6 Dave Allan 2012-01-03 21:13:22 UTC 
It's unlikely that we're ever going to get to this BZ, so I'm going to close as WONTFIX.
