Hello Team,

What is the difference between creating an instance with 4 or 8 virtual sockets, since the hypervisor has only 4 physical sockets.
My question is where do sockets, cores and virtual threads fit into the physical hardware. I think this question is not just related to Openstack, but with any virtualization.

My hypervisor configuration is as follows:

CPU(s): 192
Online CPU(s) list: 0-191
Thread(s) per core: 2
Core(s) per socket: 24
Socket(s): 4
NUMA node(s): 4

Do you have any documentation that I can read and understand better?

That we have a nice week!

Att,
