Kind of exciting to jump into some Proxmox shenanigans... Trying to get all of my ducks in a row as I assemble the hardware.
Because the 11th Gen Intel Optiplex Ultra I'm upgrading to (from 7th gen Intel) is 11th Gen, apparently there are extra hoops for Proxmox iGPU usage (for Plex, tDarr, Immich, etc).
Missing iGPU-sharing features in 11th gen Intel means I apparently can't just assign the GPU to my Docker VM and do everything there. Because then the server becomes headless (which seems silly for a PC literally mounted to a monitor). So, I need to migrate from my current Dockerized iGPU-utilizing apps to baremetal versions in unprivileged LXCs. All while trying to keep the existing data intact.
(I'm trying to heed Proxmox's instructions to not do Docker in LXCs)
