[SOLVED] [REFERENCE] - Linux KDE Plasma VM Migration Issues from unRAID

Aloha fellow Proxmoxers,

I'm jotting down a few notes, just in case anyone runs into these migration issues coming over from the unRAID world, or virtualizing in a similar fashion as I am.

OpenSUSE Tumbleweed + KDE Plasma running on X570 with NVIDIA GPU Passthrough via patched vBIOS.

This was tricky to get operational on unRAID, aside from just the ROM dump/patching standpoint, OpenSUSE has some additional frustrations with NVIDIA that Arch derivatives don't suffer from.

Migrating it to Proxmox was a longer process than I'd assumed, and this came down to two separate issues:

1. X11/SDDM/KDE (undetermind) was failing due to the inclusion of VMMOUSE related QEMU hardware emulation, I finally found a single post related to it from only a few days ago, and removing xf86-input- vmmouse resolved this part.
2. NVIDIA/Intel audio failing, due to snd_hda_intel. Initially, I verified my MoBo audio controller was already disabled, then I disabled snd_hda_intel in the Proxmox grub, and finally, also disabled it in the OpenSUSE grub, via - rd.driver.blacklist=snd_hda_intel module.blacklist=snd_hda_intel

Reboot, and voila - SDDM with a blinking password prompt, joy of joys that it wasn't frozen for the umpteenth time.

KDE and all audio + system functions appear correct, as pre-migration, hopefully with greater transfer speed now on dedicated disks, along with increased stability.

When debating ESXi vs Proxmox - the direction these products are moving in was the deciding factor, and I hope there will be wider adoption soon. It seems that a number of the YouTube content creators I follow are actively moving into Proxmox, which is exciting.

Cheers, -Ian
