Hi,
there's no option for that in OVM. If such thing is an issue, you'd probably go ahead and buy an extra OVS node, which can accomodate all guests from a failling OVS. If you really need a HA-Setup, then you'd need to take that into account - trying to save some money by monkeying around with any kind of (semi-)automatics will bite you always somewhere downstream.
This is a simple business assessment…
