Overview

In vCenter Server 7.0 Update 1, vSphere cluster services, such as vSphere DRS and vSphere HA, run on ESX agent virtual machines to make the services functionally independent of vCenter Server. However, the CPU baseline for AMD processors of the ESX agent virtual machines have POPCNT SSE4A instructions, which prevents ESXi 6.5 hosts with AMD Opteron Generation 3 (Greyhound) processors to enable EVC mode AMD REV E and AMD REV F on a vCenter Server 7.0 Update 1 system. Workaround: None
