I have the following config files on my Debian 5 dom0 with self-compiled Xen 3.3.1 and Debian 2.6.26-2-xen-amd64 kernel.

### hvm2
name = 'hvm2'
builder = 'hvm'
device_model = '/usr/lib/xen/bin/stubdom-dm'
kernel = '/usr/lib/xen/boot/hvmloader'
memory = '512'
acpi = 1
apic = 1
pae = 1
vcpus = 1
sdl = 0
vnc = 0
boot = 'd'
vif = [ 'mac=00:16:3e:11:11:01,bridge=vlan2000' ]

### hvm2-dm
disk = [ 'phy:/dev/vg0/hvm2,sda,w',
         'file:/xen/iso/ubuntu-9.04-alternate-i386.iso,hda:cdrom,r' ]
kernel = "/usr/lib/xen/boot/ioemu-stubdom.gz"
vfb = [ 'type=vnc' ]
vif = [ '', 'mac=00:16:3e:11:11:01,bridge=vlan2000' ]


I'm able to start this VM and complete the Ubuntu installation. But if after installation I change the boot device to "c", the domU fails to start. Using "cd" boots to the Ubuntu installation program and if I then select "Boot from first hard disk" I get

isolinux: Disk error 01, AX = 0201, drive 80
Boot failed: press a key to retry...

Next I booted into the installation CD's "Rescue a broken system" mode. In there I can see /dev/sda with / and swap.

Any ideas what I am doing wrong?

Martti
