Thank you, I realized the same hours ago and play currently with qemu on my machine to see if this works. The host CPU on my workstation is: Intel(R) Core(TM)2 Quad CPU Q9650 Here the Westmere cpu setting worked. On the server I configured for my customer I choose an Intel Xeon E5-2603V3 Link to the specification: http://ark.intel.com/products/83349/Intel-Xeon-Processor-E5-2603-v3-15M-Cach... regards gregor On 17/01/16 16:22, Chris Adams wrote:

I just went through trying to get Windows Server 2012 Essentials (both "original" and R2) running on a cluster with Nehalem CPUs, and it would blue-screen during install. I replicated the problem on my Fedora desktop with plain KVM set up to emulate a Nehalem CPU. When I switched to Westmere or newer, Windows worked.
This appears to be some difference between Essentials and Standard edition (I am running Windows Server 2012 Standard VMs on my cluster just fine). A co-worker searching around on the Internet also found some VirtualBox users having similar issues with Essentials.
So, with Westmere or newer CPU, I think Essentials should be okay, but don't try it with Nehalem.
