Please can you run 'dmidecode'.

This looks like the bug I reported yesterday, Xensource Bugzilla #137. I 
built Xen with PAE 'on' on a FC3 x86 platform. When Dom0 booted, X would 
not come up and gave the VBE initialization failed error. However, when 
building Xen with PAE 'off'', X works just fine.

RE: X86_64 Xorg Xfree86 issues

[David F Barrera]

I am seeing this very same problem on a FC3 x86 machine, when Xen is
built with PAE=y. The problem does not happen when PAE is not set. 

Partial test from /var/log/Xorg.0.log:

Domain 0 should have the bottom 1MB of machine RAM mapped into its
address space, and it should be available via /dev/mem.

I think dmidecode uses read rather than mmap, which suggests ioremap may
not be working. See arch/xen/kernel/devmem.c

At the moment Xorg does not work under Xen on X86-64. Havn't had a
chance to look into it...but even if you try the "vesa" driver you
cannot get X working. Basically the driver is not able to get to the
video card bios...may need a hypercall to do this.

Re: X86_64 Xorg Xfree86 issues

I get a blank screen trying to load X. I'm `init 5`ing it and letting the 
fedora scripts go from there.

AMD dual core system, 4GB ram, asus A8N-e motherboard, diamond stealth 
radeon pci video card. Running Fedora Core 4 on top of a kernel compiled 
from a daily source pull from xen-unstable on ~July 26th. Happy to provide 
more info if desired/requested for debugging. - Reuben

X86_64 Xorg Xfree86 issues

[David_Wolinsky]

[-- Attachment #1.1: Type: text/plain, Size: 291 bytes --]

I am unable to load up Xfree86 or Xorg on a Xen64 machine.  I have an
I915 (descendant of I810) and I get these messages - No V_BIOS found,
VBE initialization failed...  Any suggestions on how to get this fixed?
I have /dev/agpgart for I8xx enabled as well as the DRM.

Thanks,
David
