FreeNAS VM core affinity?

[FlyingBear]

Does anyone know if and how it's possible to allocate virtual CPUs in a VM to specific cores please? I'm running a Debian Roon Server VM in 11.2-RC1 (bare metal, not a FreeNAS VM), and would like to pin its 4 virtual CPUs to cores on one CPU of my two Xeons. The reason is that one CPU runs consistently 10degC hotter than the other, because of the Supermicro chassis layout, and I want to tax the cooler CPU with Roon.

Thanks in an advance for any help!

Bhyve can assign virtual cores to physical ones with the -p switch. FreeNAS don’t have the option in the legacy UI, unsure about FreeNAS 11.2-RC1.

Thank you. There's no obvious way to access the VM outside the UI.
