[Bug 1192131] Re: giant race in quantum - quantumclient key errors break creation of guests in nova
We haven't seen this failure in the last 7 days, so I think we can call
it resolved.
** Changed in: nova
Status: Confirmed => Fix Committed

Title:
giant race in quantum - quantumclient key errors break creation of
guests in nova
Status in OpenStack Compute (Nova):
Fix Committed
Status in OpenStack Quantum (virtual network service):
Invalid
Bug description:
The current #1 issue the in gate is a quantum key error which looks to
be a race in how quantum responds to requests from nova. This can be
seen with a representative error here:

It's very unclear what's going in quantum at this point, as apparently
only DEBUG logs are running, but not normal log levels? The fact that
this is fixed with a recheck on unrelated code means there is some
race in quantum interaction that is not accounted for from nova, and
this is a huge issue currently in the gate.
