I have two hosts with the same CPU Intel® Xeon® Processor X5650 which I believe to be part of the "westmere" generation. I have both of these hosts in a cluster and want to enable EVC. My question is, if I enable this on running hosts and specify "westmere" in EVC will it have any affect on the running VMs? Would my current virtual machines be using all the features available under the "westmere" generation without this enabled? I do have plans on bringing in a new host that will be on a higher generation so am looking to get this enabled.
