The kernel always tries to use NFS root or floppy as last resort, when 
everything else fails.

In your case its probably the SCSI hostcontroller driver that is missing or 
fails initializing. 
if you just compile with "make world; make install", it basically will use the 
plain vanilla kernel configs, without drivers for fancy hardware.

So check your kernel config for the needed driver, if its there, but compiled 
as module, try generating and using an initrd, otherwise recompile the 
kernel, statically including the driver.

(just enter the kernel source directory inside the xen sources, "make ARCH=xen 
menuconfig" should work from there)
