Xen users - Nov 2009 - Jemery''s Linux 2.6.31.6 dom0 pv_ops plus GEM KMS of Intel

Guys!

 My Linux 2.6.31.6 from Jemery''s tree is working perfectly with my
Ubuntu
Karmic desktop WITHOUT Xen... But when I try to activate the Xen-3.4.2 with
this kernel, I got a unusable system... No video at all...

 If I disable the ModeSetting with nomodeset Linux option, the system
appears to run ok but no X...

 Anyone have some tips to run Xen with the pv_ops kernel and X with Intel
drivers?!

 My grub''s menu entry:

### BEGIN /etc/grub.d/40_custom ###
# This file provides an easy way to add custom menu entries.  Simply type
the
# menu entries you want to add after this comment.  Be careful not to change
# the ''exec tail'' line above.
menuentry "Xen 3.4.2 / Ubuntu 9.10 kernel 2.6.31.6-tcmc-9.11-1 pvops"
{
insmod ext2
set root=(hd0,1)
multiboot /xen-3.4.2.gz /xen-3.4.2.gz dom0_mem=2048M
module /vmlinuz-2.6.31.6-tcmc-9.11-1 /vmlinuz-2.6.31.6-tcmc-9.11-1
root=/dev/mapper/HyperDeskVG01-tcmc--dell--root ro nomodeset
module /initrd.img-2.6.31.6-tcmc-9.11-1
}
### END /etc/grub.d/40_custom ###

Thanks!
Thiago

Hmm.. I posted a temporary work-around, look for ''Xen-devel
ttm''. The fix
is a band-aid until we get some time to look at this properly.

But with modesetting turned off, X should start properly. What does your
Xorg.conf
and /var/log/Xorg.conf tell you? Any ''writeback'' failed
messages?

With the nomodeset the Xorg.0.log file looks fine, no error reported but, I
got a blackscreen/system freeze, no GDM, no X, no console... And in Ubuntu
Karmic, there is no xorg.conf...

I''ll take a look for you band-aid solution "Xen-devel ttm"...
