Hm, that's a single socket or dual socket E5-2650 system? That CPU itself has 8 cores, and can work in a dual socket system, that's why I ask.
It is a virtual machine, and I think a property of the VM software is that any given virtual machine can only run on one socket of the underlying hardware. The real machine is dual socket, though.
