I was told by IBM sales that x3650 doesn't support windows server 2012. I feel it's ridiculous as x3650 is their enterprise model, just one level below its highest class x3850 in their system x series.
Is it possible that I use centos as host to install XEN and visualize windows server 2012. Can it be done? Vmware ESXi is great but its kind of expensive for small online company like us.
