Adding to this, i am not redirecting my boot logs to another machine. but as i observed through boot process, it is detecting all modules, even mkinitrd doesn't complain about missing modules.

Hi keir,
 
Normal kernel is booting and detecting SCSI disk fine. When i boot in Xen mode, it gives this problem. If you put search "switchroot mount failed" in Xen user/dev list, u will see this has been a common issuse with no solution posted. Yes, I also believe it is problem with xen kernel not detecting the SCSI drivers or something.
which log file u want me to check.
 
Regards,
Vineet

Does teh kernel boot output indicate that the SCSI module has loaded
and actually detected any discs (sda in particular)? This doesn't look
like a Xen-specific problem.
