Title:
  Fail to attach interface after update to Victoria

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Updated our cluster from Ussuri to Victoria and we are seeing issues
  with instances that have an interface on one of our networks. Network
  is named ext-net which happens to be the only shared + external net we
  have setup.

  Nodes are all running  Centos 8.5. Cluster was setup with Kolla
  Ansible

  When adding an interface attached to the ext-net to an existing instance I get this error from dashboard:
  Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible. <class 'nova.exception_Remote.PortBindingFailed_Remote'> (HTTP 500) (Request-ID: req-3774e75d-ce1a-4897-96f7-85b4e4884b7c)

  I can attach more logs before/after those lines if more info is
  needed.

  The controller and a handful of hypervisors have updated to Victoria.
  We only see this error on instances that are running on hypervisors
  running Victoria. I can attach an interface to the ext-net just fine
  on instances running on hosts still using Ussuri.

  Will also note I get errors when migrating an instance with an
  interface on ext-net from a Ussuri to a Victoria hypervisor. The error
  messages in that case is similar (PortBindingError), I can paste in
  those errors also but expect they are the same issue just from
  different sides so thinking fixing one will fix both.
