@hamidsattarrana,

As per your previous thread, you mentioned the following:

xeon CPU E5 2680

If that is your CPU, then the maximum level is Sandy Bridge and no Broadwell. It is also displayed here: https://ark.intel.com/content/www/es/es/ark/products/64583/intel-xeon-processor-e52680-20m-cache-2-7.... Unless you are not sharing with us the proper version (v2, v3, v4)

Also, if you want to enable into a cluster you can do it of course but for the VMs that are running on the Gold host, you will need to power them off as the vMotion will not work as they are using CPU capabilities not available on the E5-2680. If you decide to go with the cluster, you need to do the following:

  1. Create an empty cluster and enable EVC Sandy Bridge
  2. Add the E5-2680 host to the cluster (No downtime is required for the VMs running in it)
  3. Power-off the VMs on the Gold ESXi and vMotion them to the Xeon ESXi
  4. Once you finish migrating all the VMs, add the Gold ESXi into the cluster.

That way the cluster will pick up the EVC level and force the compatibility.

Please allow me to ask why you want to enable EVC on a VM. It's usually enabled on the cluster level.

This goes in chain with the following issue: https://communities.vmware.com/t5/vMotion-Resource-Management/Vmontion-error/m-p/2970555#M4859. Try to follow the same topic on a single thread.

So as per that discussion and that you are trying to migrated between a Xeon Gold and a Xeon E5-2680, you need to select the following level: Sandy-Bridge. This is like this as per VMware HCL: https://www.vmware.com/resources/compatibility/detail.php?deviceCategory=cpu&productid=25&deviceCate...
