Welcome to the Community,
What exactly is your question?
Is it about enabling EVC on a cluster with powered on VMs, or is it about live migrating VMs in an EVC enabled cluster. Please clarify.
Thank you for your answer.
Sorry about that my question for not clarify.
If I can enabling EVC on the presence of a user who uses a VM??
It is possible to enable EVC for a cluster with powered on VMs. However, you cannot select an EVC mode with less CPU features than the ones for the physical hosts while there are powered on VMs.
For a scenario where you have some hosts in the cluster, and want to add another host with a newer processor, it should work to enable EVC for the current CPU family, and then add the new host to the cluster.
Thank you for you answer !!!
Have a good day!! Thx!!
