Xen users - May 2012 - No dom0 display with Fedora 16 3.3.5-2 kernel

Xen Users,

Just checking to see if this problem has already been reported as a bug: Fedora
16 running kernel 3.3.5-2.fc16.x86_64 on Xen 4.1.2 (installed from Fedora RPMS)
will not run the GUI display on the local hardware console. Both Xen and the
dom0 kernel boot and everything else works, e.g. you can manage Xen using xl
over SSH and run guests with full GUI.

I installed an earlier kernel, 3.1.0-7.fc16.x86_64, and it does not have this
problem. Also, the 3.3.5 kernel console GUI works fine on bare metal, so this is
not a display misconfiguration and does not appear to be a Xen problem.

Has anyone on the list either made kernel 3.3.5-2.fc16.x86_64 boot up with a
local display or already reported this to RedHat as a bug?

Sincerely,

John

So you mean you can''t run X on Dom0, is that right? If yes,
that''s
weird, as I''m sending this e-mail right after rebooting my SandyBridge,
FC16-backed laptop, into that configuration (i.e., latest Linux and
Latest Xen packages which are the one you''re reporting)... And yes,
I''m
using Evolution in Gnome3 after logging in a GDM graphical session! :-P

Well, I see, but I''m not sure what it could be then, as it is working
here. What hardware are we talking about? What kind of error are you
seeing? What do stuff like /var/log/Xorg.0.log and similar say?

As said, I am running it correctly. Also, I would be rather pointless to
file a bug about FC16 as of now, with FC17 coming out in _days_ :-)

Hope to have been of some help,
Dario
