Are you sure you’re passing your gpu through correctly? This didn’t happen to me, but a buddy of mine didn’t do iommu and tried to pass the gpu through to a VM, and he couldn’t boot either. If you boot rescue and change the VM to not start-up on boot? I would definitely post your grub boot line.

Fun fact: every time I hear the work Telus, I do a little hock ptui at the ground. I could tell you stories. Proxmox and self host!

I have an old as eff laptop hiding behind my TV, and I use Unified Remote to make my phone act like a wireless mouse and keyboard for it.

Also, Proxmox is basically the answer to “I hate big tech and have a lot of time to kill. How do I deal?” Make one computer into 30 mini servers.
