[Bug 1370783] [NEW] check-tempest-dsvm-neutron-dvr instability

 

Public bug reported:

Now that the job 'check-tempest-dsvm-neutron-dvr' is running regularly
we started observing new failure modes:

This seems to have been introduced since change 114410.

Another failure mode is this one:

Which looks like to be introduced by 120885.

Revert commits have been issues to try and root-cause the issue and an
initial analysis of the results seems to pinpoint these two commits as
the source of our recent grief.
