For my cluster, I changed the bios settings to enable the AES instruction on each node, one at a time, after migrating VMs to other nodes and back when done, then I was able to upgrade the cluster CPU type to the appropriate westmere when they were all updated.
I'm not sure if something else might need enabled for libvirt and newer CPUs. As a side note, I did have problems installing Server2016 on a real nehalem CPU VM, where it would become unresponsive, so the test for newer Nehalem is there for good reason. The lack of AES instruction test is what's used to give nehalem for the cpu type.
