Thanks Sumit for reporting the libvirt XML! I asked the same thing to the original reporter of the bug. If the XML has two interfaces, this means that two ports are present in network_info - which is produced by _allocate_network. In that case we can exclude the re-scheduling issue, as the problem

We saw this issue in Grizzly as well. I investigated the Quantum logs and I did not find anything bad. The VM actually does get two interfaces in this case, so it seemed like some race condition on the nova side: Thanks, ~Sumit. On Tue, Mar 26, 2013 at 10:24 AM, Salvato

Hi, I have seen something like this with stable folsom. We have yet to be able to reproduce it. In our setup we saw that there were timeouts with the quantum service. In addition to this we had 2 compute nodes. My gut feeling was that one of the nodes has a failer and the scheduler selects ano
