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 lxterminal. I am out of wit. Any ideas? -- Christian Brandt life is short and in most cases it ends with death but my tombstone will carry the hiscore
