I have run the multimode grenade job twice:
Failed: [1] http://logs.openstack.org/69/143169/60/experimental/gate-grenade-dsvm-neutron-multinode/bf6bae1/
Success: [2] http://logs.openstack.org/69/143169/60/experimental/gate-grenade-dsvm-neutron-multinode/7c05ff0/

The [1] failed because it couldn't ssh to VM. The connectivity issue happened during resource creation phase - even before upgrade.

Regards,
Artur

The first run for the multinode grenade job completed.

http://logs.openstack.org/35/187235/11/experimental/gate-grenade-dsvm-neutron-multinode/011124b/logs/

I'm still getting my bearings in the grenade log output, but if I understand it correctly, after upgrading Neutron, when spawning a new instance we do not get successful connectivity. The odd part is we see the failure twice. Once when upgrading Nova[1], then once when upgrading Cinder[2]. I would have thought Grenade would have exited after just failing the first time. It did do a call to worlddump.

The odd part is that the first failure is a little strange - it pings then sleeps until it successfully gets a packet back. Which it does - but then it does a call to worlddump. Odd?

Anyway, then it goes on to upgrade cinder, then tries to create an instance and ssh in, then it fails and grenade exits completely.

I'll continue digging through the logs to see exactly why we don't get connectivity. I see some interesting warnings in the L3 agent log about cleaning up a non-existent router[3], which may be the culprit.
