Yup!
Exactly right.
Weirdly, I just did this exact guide.
I already had the Proxmox and a template of Ubuntu, but the rest, yup!
I am running a pihole Docker, and a SearxNG, and they both work great, on OAF hardware.
I meant to write EoL, but OAF works.
Thanks for the clarification. I cobbled together a server pc that is 14 years old now and eol. It has 8gb of ddr3 ram and a 1c 2p 3ghz processor but has an eco psu which is nice. The container efficiency will really help lol. To begin with Im going to drop jellyfin and ubiquiti management on it; then do some searching for a possible NAS solution that works with jellyfin decently.
I have Jellyfin working on it as it's own VM in Proxmox. It has a long delay before a stream starts, but playback is fine. No complaints. It accesses my media as a mount off of a different PC over Samba.
