When I try to install Precise domU PV with this xl configuration file:

extra = "debian-installer/exit/always_halt=true -- quiet console=hvc0"

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.
