Hi, I am new to proxmox. I recently migrated from another Hypervisor.

I installed pve 8.3 and updated it. Than installed a VM using ubuntu 24.04.1, due to running ollama, I wanted to passthrough the GPU (AMD). So I created a mapping for the device.

I run into 2 issues here.
1: After a couple of minutes the VM stops with an internal error and an exclamation mark in de GUI.
2: I cannot restart the VM because of probably a reset issue on the PCI bus.

I have to reboot the host to solve this.

My questions:
1: To create th mapping for the GPU I set cpu=host in the config of the VM, is this correct?
2: How do I proceed on the troubleshooting for this issue?


Oh, I just noticed I did not save my GRUB changes to enable iommu. I have changed this. Lets see if it fixed my issue.
No, that was not it.
