Description

When instantiating instances with more then 1 vcpu, qemu-kvm runs with...
-smp X,sockets=X,cores=1,threads=1
X being the vcpu assigned.

It seems to be fine in Linux guest as it can still uses more than 1 vcpu, however in Windows guest it only use 2 cores/sockets/processors. I created a VM with 16 vcpu with 16 real cpu on a dual socket server, it runs with...
-smp 16,sockets=16,cores=1,threads=1

And Windows guest can only see 2 processors despite that the license is permitted to have more than 2 sockets.

Also, I'm concerning if that is NUMA-aware.
