Hallo Jaromir,there are two ways of booting via pygrub, with various distros, I have success with different methods.
See this article of mine: https://www.root.cz/clanky/xen-na-netbsd-8-0-instalace-linuxu/ best Petr Dne 03. 04. 20 v 17:16 Jaromír Doleček napsal(a):
Hello, I'm trying to setup a Linux DomU under NetBSD Dom0 for some testing. Booting via pygrub doesn't work for me (error something like 'can't find partition'). The Xen wiki mentions pvgrub as alternative to the pygrub. I see there is pv-grub binary in xentools48, but nothing in xentools411. Anyone knows how to get it working? I found 2012 thread: https://mail-index.netbsd.org/port-xen/2012/02/10/msg007138.html Jaromir
