Sorry folks, that's kind of an email I hate writing but let's be honest : our gate is busted.
Until we figure out a correct path for resolution, I hereby ask you to *NOT* recheck in order to not spill our precious CI resources for tests that are certain to fail.
Long story story, there are currently two problems :
#1 is currently investigated by the Neutron team meanwhile a patch [1] has been proposed against Zuul to skip the failing tests.
Unfortunately, this patch [1] is unable to merge due to #2.
#2 has a Tempest patch that's being worked on [2] but the current state of this patch is WIP.
We somehow need to have an agreement on the way forward during this afternoon (UTC) to identify whether we can reasonably progress on [2] or skip the failing tests on nova-lvm.
Again, sorry about the bad news and I'll keep you informed.
