Hi,
A new wiki has been published on Cluster Emulation mode http://www.ovirt.org/Cluster_emulation_modes
Please review.

strange, I thought the EmulatedMachine config value we currently have was also used to validate host support, but seems we were missing that part.
I was also puzzled while doing git grep -i emulatedmachine
what will happen with the current EmulatedMachine config value?
The OVF builder will use the cluster config and EmulatedMachine will be deleted
what happens when cluster emulation mode changes to hosts not matching it?
Updating cluster's emulation mode is prohibited when active hosts has running VMs. if VMs are not running on them they will transit to non-op on the next refresh
the emulated machines are reported on getCaps, not getStats, so not sure what refresh you refer to, anyway i think we should allow if no vms running but all active hosts support new value and block otherwise (if vms are running or one of the active hosts doesn't support new value) iirc this is the logic for changing cpu type
