I also feel overwhelmed with HA homelab stuff.

HA on my RPI is just not reliable, requiring a reboot 4-6 times a year for reasons I don't understand. Frustration at being in the literal dark doesn't translate to the right mindset to root cause.

What I need is an opinionated guide on minimum viable virtualization, but so much of the resources online are from folks that are homelabing maximalists.

I feel the same temptation as parent to create a spartan solution.

I got myself a NUC. It's been worth it: tiny, has 16 GB of memory and 504 days of uptime.

I have servers for running VMs and containers but I felt like it would be nice to have this one as a separate device. It's also easy to plug in radio devices.

Same. The complexity of HA also leaves my family with a bus factor of one re: keeping the lights on.

Get a nuc or a mini pc: i5-8500 or better (used, ebay https://www.servethehome.com/introducing-project-tinyminimic... for a baseline of what's out there)

Ram is your friend (but prices are gross). Dont be cheap on storage.

Get an external USB drive (3/2/1 rule).

Install proxmox on said device.

Use the proxmox community scripts to install HAOS as a VM. https://community-scripts.org/categories?category=operating-...

Pass through what ever USB devices you need (or spring for POE devices ).

Enjoy your HA setup.

Proxmox is the way to go here. Once you have a working install dont over commit before you learn to: 1. back up, 2. restore. These should both be local and remote (HA can enable this to various sources).

As a bonus you now have a runtime (proxmox) that can do tons of other things (see the whole community scripts link).

I have been running HA for years now, and this method makes things a pleasure and is easy (at least if you're a nerd) and cheap (the solutions are lower power).
