In the meantime, one other user with the same problem has turned up
on the VMware forum. He reports that Windows 8 x64 doesn't work on
the E3-1270V2 host either, but a 32 bit install of CentOS 6.3 does.

Also, I have updated the last host and it continues to run all
VMs fine, so the ESXi version is definitely not the culprit.

What happened between kernel releases 2.6.32-220.7.1.el6.x86_64 and
2.6.32-279.2.1.el6.x86_64 that would cause a CPU dependent early
exception?
