Hi Nicolas,

You may be hitting a known issue with QuantumManager + DHCP + Melange:
- https://bugs.launchpad.net/quantum/+bug/949234

Looks like a partial fix was suggested for QuantumManager in Nova, but
validation ran into a possible melange issue, that ultimately was rejected,
without submitting the QuantumManager fix:
- https://bugs.launchpad.net/melange/+bug/951499

Can you try just applying the one-liner patch described in 949234 and see
if it solves your problem?  If so, we can get that merged in.

Dan
