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.

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.
