Well, the ESX driver was not designed to work that way. The current design assumes virtual machines run on ESX hosts and a vCenter is some higher management instance that is necessary for migration. But from an API point-of-view a vCenter is like an ESX host, a compute resource with virtual machines attached to it. So there is basically no problem in handling a vCenter like a single ESX server. It'll need some tweaks in the ESX driver, but most of its functions should work without changes. I would like to introduce a vpx:// scheme beside esx:// and gsx:// to refer to a vCenter. I'll take care of this after I've finished some other pending patches for the ESX driver. Adding support for this doesn't seem to be very complicated, so stay tuned :-) Matthias -- Libvir-list mailing list Libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
