I was able to dig a bit and it looks like it's still an MTU issue. http://logs.openstack.org/35/187235/14/experimental/gate-grenade-dsvm-neutron-multinode/c5eda62/logs/tempest.txt.gz#_2016-02-09_20_37_40_044 "SSHException: Error reading SSH protocol banner[Errno 104] Connection reset by peer" I tried pushing down a patch to cram network_device_mtu down to 1450 in the hopes that it would do the trick - but sadly that didn't fix. I'm going to have to keep digging. I am almost certain it's something that Matt K (Sam-I-Am) has already made note of in his research. -- Sean M. Collins
