Hi Marcus,
I am amazed how you have LVM support. Because
linux-2.6.11-xen0's configuration does n't have any
module for LVM. None of the modules in xen0's config
(all those you named in your earlier email) has
anything to do with LVM. I think LVM module is called
lvm-mod. Could you or anyone verify for me that you
have this module in your xen0 kernel? I guess this is
the kernel I should look into for LVM support.
Thanks
