i add boot order and the virtual machine still boot from hard disk instead of cd-rom <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='unsafe' io='native'/> <source file='/Linux.raw_image'/> <target dev='sda' bus='scsi'/> <boot order='2'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw' cache='unsafe' io='native'/> <source file='/xubuntu-12.04-desktop-amd64.iso'/> <target dev='sdb' bus='scsi'/> <readonly/> <boot order='1'/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> here is the captured command line generated by libvirt (uuid and mac address are masked) /usr/bin/qemu-system-x86_64 -enable-kvm -name Linux -S -M pc-1.1 -cpu SandyBridge,+osxsave,+pdcm,+xtpr,+tm2,+est,+smx,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme -enable-kvm -m 1024 -smp 2,sockets=2,cores=1,threads=1 -uuid xxxx -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/Linux.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 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x4 -device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x5 -drive file=/Linux.raw_image,if=none,id=drive-scsi0-0-0-0,format=raw,cache=unsafe,aio=native -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=2 -drive file=/xubuntu-12.04-desktop-amd64.iso,if=none,id=drive-scsi0-0-0-1,readonly=on,format=raw,cache=unsafe,aio=native -device scsi-cd,bus=scsi0.0,channel=0,scsi-id=0,lun=1,drive=drive-scsi0-0-0-1,id=scsi0-0-0-1,bootindex=1 -netdev tap,fd=18,id=hostnet0,vhost=on,vhostfd=19 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=xx:xx:xx:xx:xx:xx,bus=pci.0,addr=0x8 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev spicevmc,id=charchannel0,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 -spice port=5900,addr=127.0.0.1,disable-ticketing,image-compression=off,jpeg-wan-compression=never,zlib-glz-wan-compression=never,playback-compression=off,streaming-video=off -vga qxl -global qxl-vga.vram_size=67108864 -device intel-hda,id=sound0,bus=pci.0,addr=0x3 -device hda-micro,id=sound0-codec0,bus=sound0.0,cad=0 -chardev spicevmc,id=charredir0,name=usbredir -device usb-redir,chardev=charredir0,id=redir0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6
