Wanted to highlight two developments:
- Red Hat has expanded their free tier to 16 RHEL licenses for use in production; users unhappy with CentOS Stream could switch to RHEL for both dom0 and 15 appVMs without paying anything.
- Red Hat has a free for FOSS infrastructure program; Qubes developers shouldn’t need to worry about bumping up against the 16 cap of the aforementioned program.
I also realized that dom0 gets updated between ~1 and ~3.5 years (~1.9 years on average). If Red Hat sticks to their revamped 3 year release cycle, we wouldn’t be stuck on old kernels much longer than what we are used to. The CentOS Hyperscale SIG provides accelerated backports (slides) of specific items (like systemd) and is working on backporting LTS kernels as well (which are released ~yearly). So it should be feasible to keep dom0 on a fresher kernel in future.
