Xen Users,
In trying to bring up a new machine, I have debugged to the point that it appears that nomodeset is required to boot a pvops dom0 on Xen 4.0.1, on this machine (otherwise a udevd failure), but the video will not work without KMS, i.e. dom0 gets a "No modesetting driver detected" error. Everything in dom0 works fine remotely, including X forwarding, but no GUI on the console. I have tried all combinations of iommu, nomodeset, and nopat. I have also tried intel_iommu=igfx_off, without changing the results.
Any suggestions?
Sincerely,
John

Couple, but not sure if they apply without the data above.

Konrad,
Thanks. Domain 0 is one of Jeremy's pvops kernels, the latest 2.6.32.25, as far as I can tell, downloaded as a snapshot. The tarball called itself xen-51f9f52, but I don't know if that is a unique id. I am trying to bring this up on Fedora 14. X forwarding works just fine. I have not set up the networking properly on this box, so that will not look right, but does not matter.
Attached are the outputs from the serial console, dmesg, lspci, and X logs for bare metal and Xen boots of the dom0 kernel:

Nothing jumps at me. The Xorg doesn't boot b/c there is no /dev/fb0, but it
is present when you boot baremetal.
Can you fiddle with 'drm.debug=255' and 'i915' parameters to see if it can
output some more details?
Also, 2.6.32.25 is a bit old. You should try to update it.

Konrad,
Agreed. However, this is the newest kernel I have been able to build and boot, on the target box. I started with the latest and worked my way back down to 2.6.32.25, to get one that would build and boot. Most of our platforms are up to about 2.6.32.32 or thereabouts.
The target is an Intel DG35JO board, which is a bit old itself? It does not expose all of the latest VT-d features, so perhaps it would be better to set the whole platform aside and put efforts into getting newer hardware that can do things like SR-IOV and EPT?
Sincerely,
John

Whooooa. What are the boot issues with the newer kernels?
BTW, you hadn't provided me with the 'drm.debug=255' and 'i915..' debug options.

It should work. I've some more ancient boxes than that and they boot fine.
