Title:
  Failed to establish authenticated ssh connection to cirros - error:
  [Errno 113] No route to host

Status in OpenStack Neutron (virtual network service):
  New
Status in OpenStack Compute (Nova):
  Incomplete

Bug description:
  Saw this in the gate today, I think it's separate from bug 1349617, at
  least the error is different and the hits in logstash are different.
  The root cause might be the same.

  This is in both nova-network and neutron jobs.
