Stable Newton grenade multinode jobs fail with "Failed to connect to the host via ssh: Host key verification failed."

[Jakub Libosvar]

post-stack part of grenade fails: e.g. http://logs.openstack.org/42/399142/1/gate/gate-grenade-dsvm-multinode/a25f646/logs/grenade.sh.txt.gz#_2016-11-20_10_18_52_797

I wonder why does it fail in post-stack, when it was working on deploy:

:-?

know_hosts could have changed on the deployment node?, or the remote host changed it's key? :?

It seems like it affects Newton and/or Trusty only?

[15:49:39] <dulek> ihrachys: It's failing only on osic/rax nodes.
[15:50:41] <dulek> ihrachys: I've pinged #osic-ops on the issue, no movement from their side yet.
[15:51:03] <dulek> ihrachys: You can nag them too. ;)

2016-11-23 18:19:51 fungi jlibosva: sounded like it to me, but i'd give pabelanger an opportunity to confirm first. he seems to still be around
2016-11-23 18:19:51 clarkb jlibosva: yes I think its safe to recheck now
2016-11-23 18:20:00 clarkb pabelanger had said all the bad images were removed
2016-11-23 18:20:12 pabelanger clarkb: jlibosva: fungi: yes, I have removed the bad ubuntu-trusty images from our clouds. So, we should be good. However, if there is still failures, I may have missed a cloud.
2016-11-23 18:20:31 pabelanger we should start uploads shortly for images from today
2016-11-23 18:20:39 fungi jlibosva: as i understand it, the bug was in an older diskimage-builder release, fixed a few days ago but not updated in all our providers

Which means the issue should be solved by now. I'll recheck stable branch patches and will close this bug later.
