Can you please retry with libvirt 1.1.4?  There have been some bug fixes
in this area, and it's not worth debugging old versions if the new
version is already fixed.

considered poor netiquette to send from your employer's email if they
are going to tack on this legalese junk; and the recommendation is to
use a personal account instead.
