I don't see any duplicates from anyone else if I use those search terms. Perhaps you can provide links to some threads with people having the same issue as you?

When the boot fails, do you see any lines of output from the kernel stating that it has found a block device 'sda'? If the machine reboots too quickly for you to read then try adding 'noreboot' to Xen's command line.

Here are links to see for switch root problem ( specifically first link is exactly similar).

I have re-installed OS and xen in my system ( as i messed up  with grub when palying around it and in hope that i will rectify that error). I am not getting same error now but i am getting following error:

PCI: If a device doesn't work, try "pci=routeirq". If it helps, post a report PCI : Bridge: 0000:01:00:0
IO window :c000-cfff
MEM window : fce00000-fcefffff
PREFETCH window: e0000000-e01fffff
PCI : Bridge: 0000:01:00:2
IO window :d000-dfff

MEM window : fce00000-fcefffff
PREFETCH window: e0000000-e01fffff

I have tried pci=routeirq and apci=off, it still give me error

Yes, I know about noreboot option and I knew module were loaded and detected.
Thanks for helping me out. I have been trying to make xen work on dual core Xeon 2.8GhZ for last two days....and i have to try all options...so i am now not able to replicate same error. I am using Xen 3.0.2-2. Kindly guide me with this current error.

Regards,
Vineet

Adding to this, I have now build kernel with scsi Fusion MPT drivers builtin ( i am not sure if that has removed that error-- in fact I am not sure till this whole thing is working).

The line above is not an error. It's just useful information if a PCI device happens not to work. You should ignore it.

System hangs at this point. Any clue ?
