CPU Topology (Windows Specifically) only ever shows 2 sockets
Is it normal for Windows VMs to only ever show 2 sockets in the VM itself? For example, if I give the VM 24 cores in XCP-ng and assign the topology 12 sockets/2 cores per socket the VM only shows 2 sockets, 4 cores. If I change it to 4 sockets/6 cores per socket it will show 2 sockets/12cores per socket.

What OS version? Could this be due to licensing?
It's Windows 10 Pro, I believe I've also seen the issue with Server 2019. I don't suspect it's a licensing thing due to the fact that I could just move the topologies to 2sockets / Xcores per socket

What I have seen from Microsoft forums would seem to indicate that Windows 10 only support up to 2 sockets and 256 cores.
Windows Home is 1 socket, Pro is 2 and Workstation / Enterprise is 4 apparently......
Windows Server is many more 64 apparently, currently I have 12 dual core sockets on my VM.
Okay, this makes sense, thank you for the clarification. The reason I was asking I've been having crazy issues with xcp-ng on my server with VMs crashing all the time on boot etc and have been trying to troubleshoot and just wanted to look into this as I've done every other thing I can possibly think of. thanks again!
