Hello everyone,

I have been using unraid for easy use of vm with gpu passthrough.
However, I really wanted better VM management as well as better monitoring.

So I decided to try proxmox since underline tech stack is same as unraid.

I was able to do initial setup with proxmox without any issue and passthrough works as I expected.
However, the game that I play is giving some security warning which didnt happen in unraid

I carefully compared unraid and proxmox and realize that there are some significant difference when I spin up VM

I see some extra args as well as missing args when I launch with proxmox
What is the best approach to apply Unraid's argument with proxmox?

I tried my best to modify /etc/pve/qemu-server/<vmid>.conf to match with UnRaid's args but its not quite same.

Has anyone have any kind of suggestion in my case?


Thanks alot!

i guess you will not be able to match the unraid cmdline completetly

but the things you are missing can probably be added with the 'args' option in the config
anything in particular not working ?
