Look a flagpole

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.

It’s easy* to setup Hashicorp Vault with your own CA and do automated cert generation and rotation, if you are willing to integrate everything into Vault and install your root CA everywhere. (*not really harder than any other Vault setup, but yaknow). I may go down this route eventually since I don’t think a device I don’t control has ever accessed anything I selfhost, or ever will.

I have a wildcard subdomain pointing to my public IP, and forward port 80 to an LXC container with certbot. Port 80 appears closed outside the brief window when certbot is renewing certs. Inside my network I have my PiHole configured to return the local IP for each service.

Nothing exposed to the internet at all. There is a record of my hostnames on Let’s Encrypt but not concerned if someone will, say, deduce apollo-idrac is the iDRAC service for a Dell rackmount server called apollo and the other Greek/Roman gods are VMs on it. Seemed like a house of cards that would never work reliably, but three odd years later I only have issues if a DNS resolver insists on bypassing my PiHole. And that DNS resolver is SystemD-ResolveD which should crawl back into whatever hellhole it came out of.

They could hijack your site at any time, but with a copy of your live private certs they (or more likely whatever third party that will invariably breach your domain provider) can decrypt your otherwise secure traffic.

I don’t think there’s significant real tangible risk since who cares about your private selfhosted services and I’d be more worried about the domain being hijacked, and really any sort of network breach is probably interested in finding delicious credit card numbers and passwords and crypto private keys to munch on. If someone got into my network, spying on my Jellyfin streaming isn’t what I’m going to be worried about.

But it is why CSRs are used.

Friction between Snap and AppArmor is to be expected. The corporate sponsor of Snap, Canonical, is well known for their icy relationship with the corporate sponsor of AppArmor, Canonical.
