Big question

Has anyone here gotten an nvidia single gpu passthrough setup working in QubesOS?

Finally using Qubes OS ... wish I had dived in earlier. It forces me to do everything I kept putting off, because I was "too busy", had no time for, and a series of other terrible excuses. Now, I have to work in a manner that should be our default behaviour. A decent #learning curve, but well worth it.

@solene has a great article on using Flatpak.

Back to learning and setting up my new system...

So, one Linux distro I recently donated to is QubesOS, a distro running in the Xfce desktop environment.

One thing that I really love about this OS is the fact that instead of the basic layout one expects from a computer, Qubes focuses on compartmentalizing everything people do online into different virtual machines, and even a specialized WindowsVM for specific Microsoft applications.

I do love when I fall into rabbit holes, kind of, but today's excursion got unhealthy. As in I barely did any of the things I was supposed to do, or meant to do.

FWIW, I got a fully reproducible (as in byte-reproducible) #NixOS #QubesOS 4.3 template working. Well, working is a bit of an overstatement but I got as far as this.

Most of the work was done by evq here https://github.com/evq/qubes-nixos-template I just banged my head against the wall until my ancient memories of Qubes OS internals bubbled up, and got interested in how reproducible ext4 images could work. Anyway. I'll assemble an in-depth PR some other time (tomorrow is travel day), but I've wanted this since 2022.

There, that's one type of neurospicy that I am 🤦

Seems to me we are quickly approaching a moment in time where QubesOS, with all the elaborate and resource-draining virtualization, becomes more performant than Windows.

Qubes OS - WireGuard VPN zur eigenen FRITZ-Box

#WireGuard-Verbindungen lassen sich wunderbar in Qubes OS als eigenständige Net Cubes anlegen und VMs zu ordnen.

Damit wird es sehr einfach mehrere unterschiedliche VPN-Verbindungen zu verwalten und je nach Bedarf den VMs zu zuordnen.

Ich habe Qubes OS auf meinem Laptop getestet: Sicherheit durch isolierte VMs mit Xen – spannende Alternative zu klassischen Linux-Distributionen auf einem alten Dell Laptop.
