Subject: [Xen-users] xen 3.0.3: blank screen in xserver-xorg in dom0
To: Xen <xen-users@xxxxxxxxxxxxxxxxxxx>

I was happily using an unstable version of xen built July from source
(pre 3.0.3) and I downloaded the 3.0.3 source and built it using:
# make world
# make install
dom0 boots ok, but when the the xorg xserver starts I just get a blank
screen - I think it's not picking up the right modes.
(BTW - 640x480 does work, but it's the only resolution that works).
It's really strange, because xorg.conf is the same whether it's runinng
under Xen or a normal kernel. Here's a diff between the xorg log
starting on a normal kernel and the xen 3.0.3 kernel:

The main difference beteween the blank screen and the ok screen is that
when the display works, I get "VESA VBE DDC supported" but when it goes
blank I get "VESA VBE DDC not supported". I'm guessing that because DDC
doesn't work under xen 3.0.3 it's not picking up the right modes and my
xorg.conf doesn't work. Here's xorg.conf:
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

As I said before, my previous build of Xen works fine. Here's the
difference in the kernel config files between an unstable build of Xen
from July and the latest unstable post 3.0.3 version:

Does anyone know why this might be happening? Is it because of a kernel
difference between Xen 3.0.3 and Xen 3.0.2? Is it because of a
difference in kernel configuration?
Any help given will be really appreciated!!

Hello ,
I trie to use xen 3.03 , on a Amd64 x2 (socket am2) .
Can i do this :
Install the x86_64 hypervisor with a x86_64 dom0 kernel .
- install a domU with a i386 kernel ( in paravirtualisation mode )
- install a virtual machine in HVM mode to boot a i386 os .
- install a domU with a x86_64 kernel ( in paravirtualisation mode )
bye
