The OVF builder will use the cluster config and EmulatedMachine will be
deleted

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
