That's unfortunate. If you do a packet dump do you even see the other node's advertisements?
CARP is really at the mercy of these half-baked virtual switches; if they refuse to pass the traffic there's not much that can be done from the virtualized guest's perspective. I don't know the procedure for opening a support case with Microsoft but if that's an option it would be nice to know what their response is.
I did run into this a while back on XenServer and wondered if it would be possible to work around it by doing a GRE tunnel between the two nodes and doing CARP over that, tying it all in with scripts that are called by devd events. I have not had time to experiment and see if you can do multicast over GRE tunnels though and it's probably a very bad idea.
