[SOLVED] ZFS EFI boot(RAID 1) and intel_iommu=on boot parameter

[supermario87]

Hi,

I have this mirrored zfs install brand new and I'm 99% done in configuring it the usual way I do.

The system fully support PCI Passthrough since that a classical install with grub works

https://pve.proxmox.com/wiki/Pci_passthrough#Introduction

The part in the wiki where GRUB_CMDLINE_DEFAULT needs a change does not apply if you have a systemd-boot in an EFI environment.
I've not found a way to modify /proc/cmdline in this environment, but editing manually the line at boot time works

Any suggestion?

Thanks

Nevermind, I found the way

1. edit /etc/kernel/cmdline and ad (intel or amd) iommu stuf
2. run pve-efiboot-tool refresh
