Comment 7 for bug 1738373

We have observed this issue in stein using kolla-ansible. After a reboot of a compute node , the nova-compute docker container keeps on restarting and when looking at the logs, it's because of the "Unsupported VIF type unbound convert '_nova_to_osvif_vif_unbound'" issue.

Removing and recreating the VM throwing this error fixes the issue. Does there exist any workaround that doesn't make us delete the VM?

Our containers are running nova 11.0.1.
