Comment 2 for bug 1989748

For completeness, this is a minimal bundle which shows the issue:

series: focal
applications:
  nova-compute:
    charm: cs:nova-compute
    channel: stable
    revision: 337
    num_units: 1
    to:
    - "0"
    constraints: arch=amd64
    storage:
      ephemeral-device: loop,10240M
  ovn-chassis:
    charm: cs:ovn-chassis
    channel: stable
    revision: 21
    options:
      enable-auto-restarts: false
machines:
  "0": {}
relations:
- - ovn-chassis:nova-compute
  - nova-compute:neutron-plugin

The culprit is enable-auto-restarts being false, which sort of makes sense since I figure installing neutron-ovn-metadata-agent would cause some things to restart.

We are trying to work around this by manually installing the package and will post if this is valid.
