I've never got past the stage of using pre-packaged kernels, so this 
could be a bit "blind leading the blind" here ...
Did you compile in all the modules you need, or if not, did you 
create an initrd to go with the new config ?
Did you update the bootloader ?
Does it show anything at all when you try and boot ?

In my (very limited) experience, you should get some output as the 
bootloader loads Xen and runs it - Xen should log what it's doing. If 
the kernel is bad then things will stop after Xen loads.
If the kernel is OK, but there is no initrd (or it's bad) then the 
kernel will try and load but will halt at some point when it's unable 
to do something important.
If you're getting absolutely nothing at all, then that suggests 
either a bootloader problem or a bad Xen imgae to me.

WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon 
part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a 
dead HD and need this CD so I can replace the disk and re-install the 
printer OS on it. If anyone knows where I might get hold of one I'd 
be grateful - requests to Canon drew a blank, it's been out of 
support for years.
Alternatively, if anyone has one of these and would let me image 
their hard disk ...
