Seconding Obsidian LiveSync. Fabulous plugin + container

Interesting. I'll dig a little more then. Most of my vm experience has been on desktop for various reasons, and it's almost always been a pain in the ass and not worth the effort.

I assume the kvm stuff can be running a minimal os, sort of like an alpine docker image?

For the most part, this old bucket is doing just fine with probably more than I should be throwing at it.

I'm curious as to why proxmox and VMs over a minimal Debian install with docker containers, though? At least, from my understanding, proxmox would be requiring a lot more hardware overhead when I'm mostly just running emby/jellyfin, nextcloud, homeassistant (and related services) and frigate (with a coral).

It's definitely a lot, but I also rarely see cpu use over 70% (typically much lower), though frigate likes to cause problems occasionally. And I've never seen a concerning amount of ram usage.

Definitely getting one of those little n100s soon, and will probably move the home automation stuff over there, and slowly transition the current box into being a nas and nothing more.

I think you're right. I'm just trapped in the cycle of over-thinking and second guessing my knowledge and capabilities.
