Threadripper Virtualization

[Captinjigglesworth]

Hello all,

 

I was trying to virtualize my Threadripper 3990x and I run into the problem of only being able to virtualization half of the cores in hyper v eve n through it has the full 128. I also tried vmbox and got the same max of 32 cores. is there anything in the bios i need to change?

What error does hyper-v give when you try to give it move than 64 vpus to the guest?

 

Try using 1909, ltsc isn't made for new hardware.

 

Whata guest os?

Thats the thing it doesnt give an error it shows 128 cores and pinns all to 100% but in host, ity only uses half. guest was tried as windows 10 ent and ubunto 10.04

Try upgrading to 1909, ltsc doesn't like new hardware.

Also try a different hypervisor like kvm or esxi, or hyper-v server. to see if its a hardware issue

I was thinking of trying windows server because I ussumed server had better scaling over many cores and numa nodes.

The kernel of the systems is about the same, so I dont think there would be a big difference, but might aswell try. Also try linux. I know linux can provide a guest with >128vcpus with kvm.

Thank You very Much

Hi, I am having similar issue with my 3990x. I am using W10 pro build 2004. Did you figure out how to fix this issue?
