Hi,
It''s been a while since I tried, so I decided to upgrade my system
again to the latest Xen (3.0.2), and see how far I can get with a X
session on a dom1, using a second graphics, usb and audio card.
After reading about Bernhard Kuhns configuration I got optimistic
about getting this configuration running.
(see http://wiki.xensource.com/xenwiki/CoolConfigurations )
However, I don''t seem to be able to get passed the console tty
issue, which X somehow still seems to be needing:
Fatal server error:
xf86OpenConsole: Cannot open /dev/tty0
I tried creating the device with mknod, but although it now exists,
X is still not able to open it. (tried a cat /dev/tty0, didn''t work
either,
so I guess the device really doesn''t exist in Xen dom1 ).
Bernhard seems to have managed to get it to work somehow...
Anyone know how?
Since I do have the necessary hardware available in dom1, is there a
way to get the console working in dom1 with my second graphics card
and the usb keyboard? I would not mind hacking the console driver
a bit to fix this (although I''m not familiar with it, so might be a
while
before I get anything usefull).
Warm regards,
Mark.

I was using Debian Sarge for Dom0 and DomU and found various suggestions (with google) of things to try, most of which didn''t apply to the version of X in Sarge. Upgrading through to a more recent xorg either from unstable, or using backports.org led to much happier experiences. With xorg and the command: X -novtswitch -sharevts vt1 I then ran into more standard problems with the X display driver talking to the graphics card. Full details on what we were looking for are in my previous posts here, under "X11 on domU", but, briefly, we want multi-head/seat on a single box using the on-board AGP and additional PCI graphics cards, using USB for input devices (sound not required). We''re actually after 3 domU''s each with their own X and no console on the dom0. Using the pciback driver it was fairly straightforward to present domU with graphics and USB, though Xen needed a little tweak to make the VGA memory range available to the driver (I had help with this, so I only partially follow it :) Ultimately I had two problems getting it to work, one was the i810 driver accessing memory, which stopped X working in domU at all, the other was the second card I had installed turned out to cause display corruption when in X (but had no visible effect on the console). The final problem is one of time, which is why I can''t actually say I''ve done it, as yet :) X11 in domU, yes, but not two at once. -- Regards, Julian Davison, ICT Technician Christchurch Boys'' High School http://www.cbhs.school.nz/ _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
