My guess would be that something do with device handling is different...


If you add a "noreboot" option to the line in grub.conf with
kernel=<some place>/xen-<some version> 
Perhaps, if you have access to a second machine, also use "console=com1"
and "com1=115200,8n1" and "sync_console"  and connect the serial port of
the Xen-system to another machine, running for example Minicom or
Windows Hyperterminal to see what's being written - this makes it easier
to capture the output from the console. 

My guess would be that it doesn't find the root device or crashes during
"init".
