You CML probably wrong you can't define interface two times -drive id=volume_drive,file=volume,*if=virtio*,media=disk /first time/ -device virtio-blk-pci,drive=volume_drive,id=volume /second time/ Would you please try the following two methods 1.Use -drive&-device /usr/libexec/qemu-kvm -drive id=root_drive,file=root,if=none,media=disk -device ide-drive,drive=root_drive -drive id=volume_drive,file=volume,if=none,media=disk -device virtio-blk-pci,drive=volume_drive,id=volume 2.Just use -drive option #/usr/libexec/qemu-kvm -drive id=root_drive,file=root,if=ide,media=disk -drive id=volume_drive,file=volume,if=virtio,media=disk -drive file=/root/zhangjunyi/rhel5.6-virtio-64.qcow2,if=none,id=test,cache=none,format=qcow2,werror=stop,rerror=stop -device virtio-blk-pci,drive=test Yeah, with if=none it works great.
