lxd vms using OVN networks get different IPs on mass reboot

I have a scenario where I am using juju deployed on LXD vms in a microcloud setup and rebooting a single vm mutliple times does not result in an ip change but rebooting a physical host results in almost every vm on that host getting a new ip, even with volatile.eth0.last_state.ip_addresses being set.

Versions:

    lxd: 5.21.1-10f4115
    microovn: 22.03.3+snap0e23a0e4f5
    microceph: 0+git.4a608fc
    microcloud: 1.1-04a1c49

subscribing field high as a workaround exists.

Subscribed field high since we can workaround with lxd device overrides (in terraform as well).
