I was running Proxmox on my home server and now I am trying to switch to TrueNAS Scale. I did run into a problem with passing devices into the VM.
I did remember I had the same issue on Proxmox, but I was able to separate the IOMMU groups by adding “pcie_acs_override=downstream” to the kernel boot commandline.
I tried to edit “/etc/default/grub.d/truenas.cfg” and ran update-grub afterwards, but after a reboot the file was overwritten. What is the correct way of modifying the grub commandline? Also it would by nice to have a GUI option for ACS override.
