This is sort of related to this topic. It sounds like CS relies on vCenter for HA.
How about for XenServer and KVM? I don't think KVM has any notion of HA, so I assume CS handles it for KVM. Is that true? With XenServer, is CS the only entity that handles HA or can that be enabled within XenServer and CS is OK with that (as long as it is perhaps not also enabled within CS)? Thanks!
