Two isolated cores are being used with their VM turned off.

Hey.

I isolated the last 14 cores of my 3900x (from 5 to 23).

When the VM that uses them is powered off, I see light but constant usage on 2 core s(cores 6 & 9).

I've double checked that nothing but that VM is pinned to that CPU core.

All dockers are pinned to other cores (non-isolated ones).

Any idea where can I start to look to debug this?

Thanks.
