Mostly just as a wrapper for Docker. The main issue I’ve run into is Docker’s union file system functionality doesn’t work when backed by ZFS, so disk usage can balloon out of control. I wouldn’t use this in production but don’t tell me how to live my life mom.
Beyond various Docker stacks I also have a Certbot container that uses Snap (sigh), and Hashicorp Vault container which runs as a vanilla SystemD service. I run Wireguard as part of my OPNSense VM. That’s something I would run in a VM since it’s exposed to the internet. I have an older MinIO and Concourse CI Docker Compose config that I’d love to run in LXC but I suspect that isn’t realistic.
Note on Vault, I haven’t been able to get mlock to work (used to prevent sensitive memory from being swapped). By all accounts it should just work in LXC, but since it isn’t and there’s no swap on the host I just turned it off. I may migrate Vault to a VM at some point.
I’m personally just interested in lightweight environments with good enough isolation and don’t break all the time over nothing. Docker mostly accomplishes that for me. LXC + Docker also mostly accomplishes that.
(My heart yearns for FreeBSD Jails but with decent tooling)
I’m not going to watch the video, but what’s the procedure for switching between Linux and Windows? Usually you dedicate a GPU entirely to VFIO, with a 2nd GPU for the host OS (or run headless).
Anyway, will it work? Yes, minus some anti-cheat software. Will it be a simple solution? Well, once you get things stable, yes. The tech behind this is mature, but it can be a rabbit hole.
I would look into a non-Nvidia GPU for your 2nd PCIe x16 slot (x4, shared with the 2nd M.2 slot FYI). Good idea to check IOMMU groups before buying anything, but modern AMD motherboards are usually fine. Blacklist the Nvidia drivers and dedicate the 3070 to VFIO to make your life easier, and run Linux off the secondary GPU. Intel A380 might be a good choice. Do gaming stuff on Windows and stream via Parsec/Looking Glass/Moonlight+Sunshine; everything else on Linux.
