I am, Intel GPU on one node, Nvidia 1080 on another, works the best.
Env on both nodes:
Proxmox Hypervisior (Debian
- Debian VM testing (bookworm), though bullseye would have been fine
-- Docker on the VM
I use PCI passthrough for the GPU hardware in proxmox, that was the trickiest bit to setup, but rock solid once done. For the NVIDIA VM I use the nvidia runtime in docker.
I do up to 6 simultaneous transcodes on the nvida node, get over 100fps per transcode. Runs overnight transparently, never have an issue.
