Setting specific processor cores.

So I run some ark servers on bare metal. Looking to combine them with a proxmox server I have. But looking into it it seems proxmox does not like giving exclusive access to processor cores?

More specifically what I want to have is a dual E5-2690V4 system. Dedicate one full processor to a windows server machine for ARK and the other processor can be shared between whatever. Then inside of windows I set each ark server to its own pair of cores.

But a brief search seemed like this was not easy on proxmox?
Keywords to search for a "core pinning" "cpu affinity" and "NUMA".
You will find stuff like this:

So yes, this is possible but most of the time PVE will do a better job if you let it hypervise and dynamically manage its ressources.
That looks like what i need. Thanks.

In most cases i would not but when running multiple ark servers they are known to trample each other. I'm running 12 ark servers and each needs 2 threads. (Well they can use a 3rd if you have enough network traffic but i don't.

This way when server 4 does a world save it won't screw with server 9.
