I love virtualization in Linux and I would like to have operating system which will work only as minimal, air-gapped as much is possible host for my guest operating systems. Qubes OS project really interested me but it’s based on Xen hypervisor so it might cause troubles with GPU Passthrough which is really important for me also I’m more interested in KVM. In my case it’s not only about security and privacy but also about fun and learning. What can you recommend? I think that good choice might be Gentoo Linux because it allows for minimal installation and remove unnecessary software like CUPS, Bluetooth entirely with flags which will be great option for host only OS. But I had experience with Gentoo and it’s not easiest way 😅 Debian might be easier option but I will have less control over my system. Maybe you have other interesting options?
That’s what I’m thinking about but I think that OpenSUSE or Fedora might be too much bloated. Someone recommended AlmaLinux and I think that might be a great solution.
Alma is an LTS enterprise distro so gets pretty out of date after some time, and I don’t think it is significantly more bloated than Fedora because AlmaLinux is downstream of Fedora. Just uninstall the apps you don’t want on install. Even better is openSUSE Tumbleweed because the YaST installer allows for you to pick and choose every package (or group of packages) that makes it onto your final system.
