Bug Description

This bug is same as https://bugs.launchpad.net/nova/+bug/1324041.
Bug #1324041 has been closed, so i create this bug.

Bug #1324041 has been fixed, but the 'plug' function has changed in commit:745f5fbb3a1b0a42eb54e2be2ecfffca3cbbb872.

This commit imports the bug again in nova.network.os_vif_util:nova_to_osvif_vif method.

I find this bug in my Pike enviroment, but i think it also exists in master.

The bug log is:

This bug is also present in ocata release.
I confirm also that https://review.openstack.org/529249 worked for me.

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.

My latest comment references https://bugs.launchpad.net/nova/+bug/1809136, which is a very similar bug, with error message "Unsupported VIF type unbound convert '_nova_to_osvif_vif_unbound'"

After checking, my rocky (not stein!) nova-compute containers weren't running with the fix mentioned in the relevant launchpad (https://opendev.org/openstack/nova/commit/7b4f5725f821ef89176ef69f036471eaaf8a6201), so once I updated it manually with the fix, after a reboot the issue stopped occurring. :-)
