Is it possible to tell unraid to use a different core than cpu0

[fadynakhla]

I recently upgraded to a 7950x3d for the increased core count and additional L3 cache when gaming. The chip is split into two CCD's with 8 cores each, only one ccd (cores 0-7) has the stacked L3 cache. I would prefer if unraid used a core from the second ccd and assumed that if I isolated the first 8 cores for VMs unraid would automatically switch to using core 9 but that wasnt the case. I still saw utilization on core 0 with no vms running and also experienced some unresponsiveness/instability. Is there a way to manually change which core unraid uses to something other than 0?

As far as I know you cannot stop Unraid from using core 0 (and any hyper-threaded companion core).   I think is is built into the Linux/kvm level.

Got it thanks! Ill have to just isolate 1-7
