I didn't mean any install kernel - just a (domU capable) linux (oder BSD) 
kernel (i.e. the same kernel file as you use WITHIN the DomUs).

This should boot as before, except that you have to give kernel options by 
your xen domu config instead of the grub-conf within your DomU (pygrub is'nt 
used then). I.e. add a:

root="/dev/sda1 ro"
kernel="/full/path/to/myDomUsLinuxKernelFile"

(but make shure that the kernel file is not gzipped or similiar). If you need 
a ramdisk, do the same with it (copy it to the Dom= and configure it in the 
DomU config) like:
ramdisk = "/full/path/to/my/myDomUsLinuxRamdiskFileinitrd.gz"

but this could be zipped (if originally).

to your DomUs config when booting with "kernel=" from it - but use the correct 
device path/node instead of /dev/sda1 in my case.

This should print out possibly more details from the DomUs side if not work 
(or just work, if pygrub is the source of your problem here).


hth a bit.
best regards,


Niels.
