Bug Description
When using OVN and no explicit nameserver settings are made for a subnet, instances on that subnet will not have working DNS resolution. The reason is that in this case OVN announces the resolver addresses being used on the host to the instances, and with systemd-resolve being used, that address will be 127.0.0.53, which cannot be reasonably used by an instance.
The solution is to specify one or more nameserver addresses in ml2_conf.
