Comment 3 for bug 735974

I also got this error, and the symptom is exactly the same with Kevin's case.
I tried trunk rev 912 and rpm packages (openstack-nova-2011.2-0.31.bzr912...) by GridDyamics.

One of my colleagues says that vm launching process proceeds in case of trunk rev 905. Thus, I guess the problem would be between rev 905 and 912, and maybe another bug.
