Debian Squeeze, libvirt 0.8.3, qemu-kvm 0.15.5

After configuring the cd image the bios screen shows:
(tested with virsh, virt-install and virt-manager)

Starting SeaBIOS (version 0.5.1-20110523_174945-brahms)

Booting from CD-Rom
65MB medium found (bzw. whatever size)
Boot failed: Could not read from CDROM (code 000c)

the cd images (debian6-cd1, debian6-netinst, debian6-buisnesscard) have
the correct md5sum an can be mounted, they simply do not boot. On the
other hand, a recent knoppix ISO works well. Tested countless times. All
access rights are 777.

Only special feature: the host is a minimal installation done with
debootstrap and contains not much else than libvirt, virt-manager and

I am out of wit. Any ideas?
