I am using an Epyc 9654 CPU, and in bios have set NUMA nodes per socket to NPS4 and enabled ACPI SRAT L3 Cache as NUMA Domain, yielding 12 NUMA nodes. I want to create a VM with 12 NUMA nodes with cpu pinning, the relevant conf file entries are:
memory: 120000
sockets: 12
numa: 1
numa0...
If you go through the list of pci devices then you may be able to identify a controller you can pass through to the unraid vm. This is personally what I do but I have a server motherboard.
