Hello!

I would like to start with I am very new to proxmox and am currently trying to get into it. However, I have been having a very hard time trying to enable GPU passthrough so I can have my own local AI. I have followed the guide below and am still having trouble with it.

When I add my GPU to a pre-existing VM of base windows, I get this error in the task history.


swtpm_setup: Not overwriting existing state file.
kvm: -device vfio-pci,host=0000:01:00.0,id=hostpci0.0,bus=pci.0,addr=0x10.0,multifunction=on,bootindex=103: vfio 0000:01:00.0: failed to setup container for group 12: Failed to set group container: Invalid argument
stopping swtpm instance (pid 1919) due to QEMU startup error
TASK ERROR: start failed: QEMU exited with code 1


I have been trying to figure out why it wont boot, however I figured I would ask people who are more knowledgeable on the subject. I have a 5060 TI as my GPU, if you need anymore information below to help me with my issues please let me know, thanks!
 
Hi, @myron1
Have you read the official Proxmox documentation on this subject first?
Have you searched this forum?
Just yesterday there was a thread about GPU passthrough.

I was unaware of official proxmox documentation existed to be honest. When I get home from work I will read about GPU pass through. I have searched the forum, however I haven't found anyone who's having the same issue as me regarding this.
