you need to add an new line after line 90, then it works...

i have now trouble with the kernel as xen domain,

xen-create-image --size=4Gb --swap=1Gb --hostname=SAMBA2 --ip= --netmask= --gateway= --dist=lenny --fs=ext3 --kernel=/boot/vmlinuz- --memory=356Mb --passwd --role=udev --dir=/home/user/

but i was unable to build a runnable xen domain

i copy manually

DOM0:~# mount -o loop /home/userle/domains/SAMBA2/disk.img /mnt/
DOM0:/mnt# cp -r /lib/modules/ lib/modules/

Let me know if you're still having trouble with it.

hmm, i got an error

You can download a tarball of the kernel source from kernel.org, or you can 
check out a copy via git.  Here are the basic steps:

   wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-
   tar xzf linux-
   cd linux-
   git apply pvops.diff

 From there, you can proceed with building the kernel as you normally would.  The 
"pvops.diff" referenced above is the diff attached to the original xen-devel 
e-mail I sent:


There are two parts to the diff: one part allows you to configure the block 
device names arbitrarily and the other part adjusts the hvc console in the same 
way.  You might want to remove the portion of the diff related to the console 
as it's probably not necessary for your system.

If you don't mind using a custom kernel, you can patch it [1] to ensure that 
your disks appear as sdX rather than xvdX.
