Why would you not want the vCMP hosts to be able to config sync though? If I make changes to a guest on one vCMP guest, like add a vlan, then I would want that change to sync to the other vCMP guest on the other host in the event of a failover?

Ok that makes sense. Sorry I am just struggling to wrap my head around the vCMP concept. First time dealing with this. In previous situations my companies have just purchased new HA pairs for expansion. How does the networking work for vCMP guests? So they share links with the hosts? Currently I have 1.1 from each host connected into my PCI zone and 1.2 connected to a downstream failover switch for HA. So when I look into the vCMP guest I see interfaces 0.3 and 0.4? What does that mean? Should I be using a HA vlan within the Guests like I would the hosts if vCMP was not configured?
