Try using libvirt 1.0.0, the version you built has a bug in its LXC
support causing the error you see.

Thanks Daniel, libvirt 1.0.0 imposed too many extra dependencies on my CentOS 6.3 system. 

I downgraded libvirt to 0.9.8 (CentOS 6.3 shipped with libvirt 0.9.10), and it seems to be working with LXC and OpenStack. At least, it is can successfully launch and run LXC instances.
