Comment 7 for bug 1754682

I know you've destroyed and are about to redeploy with latest wares, and the following relates to the initial deploy referenced in this bug. But pasting observations thus-far:

The traceback in the uploaded file is completely different than that shown in the bug description. While it may be related, I'd like to see the unit log and keystone deamon logs for the same timeframe matching the traceback from the bug description (or a repro of that).

Also, I'm not able to determine what the .166 address is from the model status or bundles pastes, but this is a problem:
ssh: connect to host 10.243.8.166 port 22: Connection timed out

This could be a network or MTU issue. If the issue it recurs with port 22 connect timeouts, please confirm switchport MTUs are high enough for NIC MTUs and container interface MTUs.
