Why not walk down the wider path, using GNU/Linux as DOM0? Well, if you like the kernel Linux, by all means, do that! I prefer an well-engineered kernel, so I choose NetBSD. [...]
Unfortunately, NetBSD's installer now fails on many PCs from 2010 and later. [...]
Update 2018-03-11: I have given up on NetBSD/Xen and now use Gentoo GNU/Linux/Xen instead. The reason is that I ran into stability problems which survived many NetBSD updates.
You have to have a heart of stone not to laugh out loud.
P.S. Use KVM already, sheesh.
P.P.S. This fate also awaits people who don't like SystemD.
