Co-locate VM on a single/set of core(s)

I'm trying to understand certain impacts of virtualisation on performance by running benchmarks on VMs. I'm considering ESXi and Hyper-V as the hypervisors.

What does a Memory Device 1 A 4 yellow health status in Vmware mean?

This would mean bringing down our main server so before I do this I'd like to hear from you guys if this is the correct path. At this point there has been no noticeable degradation of server performance.

Can I map multiple AD groups to multiple roles on ESXi?

I have an AD joined ESXi server (v7.0) without a vCenter server. I can map an AD group to the "Administrator" role by configuring the advanced setting Config.HostAgent.Plugins.Hostsvc.EsxAdminsGroup. But is that all? Can I not map an AD group to the "Read only" role, for example?
