Just wanted to make sure I'm understanding this right.
I've got 2 hyper-V servers, 1 hosting 6 VMs, another hosting 2.

Do the 'sockets' apply to physical sockets on the physical hyper-v hosts, or to the virtual sockets assigned to VM's?

According to this article it seemed to me like it applied to physical, but the documentation wasn't clear.
