Reco, help me understand something: I don't understand why it
matters what distro you chose for your xen dom0, or why it makes a
distro better to have a dom0 xen kernel...
My understanding of xen is it sits between the metal and your
guest operating system(s). My understanding is there is a Linux host
operating system, but its sole purpose is support of xen, and that's
all it does. Here's a list of operating systems with xen dom0 kernels:
http://wiki.xenproject.org/wiki/Dom0_Kernels_for_Xen
By the way, the preceding page states that Fedora, from v16 on, has a
dom0 xen kernel.
To my way of thinking, the dom0 OS isn't really being used as an OS at
all: It's just an enabler for xen, and to my way of thinking, that
means it has way fewer challenges than a normal OS. So if it uses
systemd, so what? It's not like you have to worry about running Gimp or
Gnome or KDE or various authentication facilities directly on it: It's
a vehicle for xen, no more, no less.
I went to a Xen talk, and as I remember the guy said Xen is developed
and tested on Ubuntu, so that's your best bet. Yeah, Ubuntu will have
systemd, but if it works for the xen people, it should work for us all.
If one absolutely wants to avoid systemd, NetBSD has a xen kernel
available.
Unless I'm vastly misinformed, once your dom0 xen is installed, you can
now install domU hosts of any type you want, with or without systemd,
and use them to your heart's content.
Am I understanding the situation right?
