My understanding is that Proxmox on ext4 uses grub, while Proxmox on zfs uses systemd-boot, so the kernel options "intel_iommu=on iommu=pt" are placed in /etc/kernel/cmdline instead, and you apply changes instead with "proxmox-boot-tool refresh".thank you !
but i'm on zfs, would it not work?
I don't think anything changes with respect to the kernel modules.
