    Add tests for bug #1800511

    In Rocky, we started including the MTU for networks when vif_type
    is bridge or tap and libvirt >= 3.3.0, however this also meant
    that we started specifying the MTU when doing live migrations.

    It seems that the guest ABI changes when setting the MTU which
    means that live migrations will fail. This broke the live migration
    of any instance that was launched prior to upgrading to Rocky, as
    it was not loaded with the ABI having host_mtu specified.

    This is a passing (negative) test-case which will include a follow
    up patch that contains a fix and correcting tests.
