The vmlinux and initrd take from here:

/mnt/vm/disks/PRECISE.disk1.xm exist, domU hvm with raw disks
works
Is xen bug, kernel bug or my error?
Thanks for any reply

Hello,
I think that the raw parameter isn't needed and is the reason for
the device connecting error. Another way to install the guest would
be to use debootstrap. This definitly works.
Best Regards
