My server runs Debian VMs in Proxmox on an i7-2600 which has a lower benchmark than the 6600k. I also used the Perfect Media Server guide, and have 2 x 8T data drives pooled with MergerFS and 1 for parity, these are passed through to the main VM from Proxmox with ‘qm set’. One thing I often forget after deleting/restoring this VM is to run qm set again after restore, ensuring it has the flag to not back up those drives or else backups will fail and I have to go uncheck the backup option to fix it. If I need to spin up another VM for tinkering it’s also easy enough to mount the NFS share as a volume with docker compose.

Proxmox rarely shows CPU usage go above 50%, and this handles the whole *arr stack plus usenet and torrents in a single VM and compose file. I don’t even have GPU passthrough setup because the motherboard on this older rig didn’t support something like IOMMU. Never had issues with Plex or Jellyfin transcoding for Chromecast.
