Hey Sean,

Tomorrow morning UTC, we'll be discussing Neutron topics at the Nova mid-cycle. Wondering if you might give us a quick status update on where we are with the Neutron devstack grenade jobs and what your work has uncovered on the Neutron side that might be possible to discuss in our midcycle meetup?

Lemme give you some update on the matter.

We experienced some grenade partial job failures in multinode when creating initial long standing resources:

https://bugs.launchpad.net/neutron/+bug/1527675

That was identified as an MTU issue and to be fixed by a set of patches:

https://review.openstack.org/#/q/topic:multinode-neutron-mtu

The only needed piece not in yet is: https://review.openstack.org/267847 (we need someone from infra to give second +2)

With that, we pass past the resource creation phase and run actual tests with 3 failures. You can see latest results using the following fake patch: https://review.openstack.org/265759

Failure logs: http://logs.openstack.org/59/265759/15/experimental/gate-grenade-dsvm-neutron-multinode/6c1c97b/console.html

All three tests fail when ssh-ing into an instance using br-ex. This may be another MTU issue, now on br-ex side. We have not identified specific fixes to merge for that yet.

Hope that helps,

Ihar
