Comment 89 for bug 1734320

Copying here my comment on neutron patch https://review.opendev.org/640258/: not sure the failures are related to DVR: it seems we only run full tempest set with dvr enabled (with OVS). Test failures are mostly about VM not becoming ACTIVE (stuck in BUILD), I guess due to neutron VM port not becoming ACTIVE. This should not be affected by DVR in any way. Also in ovs agent logs I see errors on ovs-vsctl operations with ports having ofport -1.
