Hello, I'm using libvirt to manage my VMs and configured one VM to boot from a CDROM connected via virtio. This does neither work with QEMU-1.1.2 nor with QEMU-1.5; neither with SeaBIOS is 1.7.0 nor 1.7.2.
/root/qemu-1.5.0+dfsg/qemu-build/x86_64-softmmu/qemu-system-x86_64 \ -M pc-1.1 \ -enable-kvm \ -m 1024 \ -smp 1,sockets=1,cores=1,threads=1 \ -name ucs31-64-xxx \ -uuid 1dae3236-23e8-c87f-ec7b-9f82060fcc72 \ -nodefconfig -nodefaults \ -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/ucs31-64-xxx.monitor,server,nowait \ -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc \ -no-shutdown \ -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 \ -drive file=/var/lib/libvirt/images/ucs31-64-xxx-0.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=unsafe \ -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0 \ -drive file=/root/ucs-3.2-0/./virtualization/univention-kvm-virtio/virtio-win-0.1-30.iso,if=none,media=cdrom,id=drive-virtio-disk1,readonly=on,format=raw \ -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x6,drive=drive-virtio-disk1,id=virtio-disk1,bootindex=1 \ -device usb-tablet,id=input0 \ -vga cirrus \ -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 \ -sdl Is this supposed to work or must a bootable CDROM use the ide bus? I ask because if this is not supposed to work, I need to modify our admin to to prevent CDROMs from being added through virtio by default; later on when Linux is installed, the CDROM works fine through virtio.
