ssh connection refused after vm stop/start

[Jaroslav Henner]

Quite often, the tempest ssh tests fails, probably because of some problem with loading user-data served on the network. My theory is that the ssh is started after cloud-init in cirros, and this causes connection reset.

I have found that many logs in the gat exhibits similar message as ours, but many of them are in PASSED. I think not many tests are relying on ssh, but many are starting VMs, so we have high SUCCESS ratio. The querry:

From the logs, it seems the instance-id seemed to be available, which makes me think this is some race in neutron and/or nova, but I can't really tell

The most interesting part of the logs (console-log):
