Having been using EL7 since the first public beta, I don't agree with
some of the points raised. Specifically, there is no requirement to use
Gnome 3 - I am a KDE user, and that works fine. The biggest desktop
related problem I found is a bug in gnome-terminal that causes it to
shrink to 1 line and about 10 columns when started under KDE. Incredibly
annoying, and the bug fix for this was pushed back from the release
version despite being reported within days of the public beta shipping -
but not exactly a show-stopper (you can resize the terminal to whatever
size is required afterwards).
systemd does still handle legacy init.d scripts.
Having said that, I do detest systemd - it is a major pain in the
backside and IMNSHO an epic leap backwards, all for the sake of shaving
a few seconds off the boot time and making sure that you get a login
prompt even if an init script hangs (so it's less obvious it failed and
you don't have to boot with init=/bin/bash to fix it - boo #"$%!&* hoo).
And don't get me started on grub2.

I've been meaning to do this on my backup virtualization system. The
only problem is that I have to find time to actually build it (all the
parts have been sitting on my work bench for a while now).
Having said that - what could possibly be causing such a show-stopping
problem? Xen tools are pretty self-contained. Xen runs underneath dom0,
and I am starting with the assumption that the kernel will need to be
changed anyway. Over and above that, the only possible problem could be
in userspace. If it is in userspace, what is the actual problem?

Things have, sadly, been going in that direction for quite some time
now. Fedora is now pure cowboy-hacker-space, and it is directly
impacting EL by lowering the standard of the starting point.
