From the above config file you've editted it beyond that created by default 
using the Xen tools in SLES 10. I'm assuming there is a reason for this. Can 
you clarify what it is exactly you're trying to achieve with this VM? (Beyond 
getting it to boot I mean) Judging from the extra settings it looks like 
you're trying to boot to single user mode in the equivalent of the 'Safe 
Settings' from the SUSE grub menu?

The line above confirms what Amos had mentioned. The first extra (1) parameter 
for the kernel boot options have been overwritten by the subsequent 
parameters.

128MB of RAM is really very little for SLES 10 (I know the installer will 
likely fall over with this amount of RAM). Can you try increasing this amount 
at all? If you're booting to single user mode, are you trying to perform some 
disk checks or such on this instance? You could always lomount the disk image 
if it's access to the disk that you require.
