If add rerror=stop in cli, QEMU will not core dumped but quit with promt "rerror is not supported by this bus type". e.g:...-drive file=/mnt/my-data-disk.qcow2,if=scsi,id=drive-data-disk,format=qcow2,cache=none,rerror=stop,werror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x7,id=scsi0 -device scsi-hd,drive=drive-data-disk,id=data-disk,bus=scsi0.0 -k en-us -boot menu=on -spice disable-ticketing,port=5931 -monitor stdio qemu-kvm: -drive file=/mnt/my-data-disk.qcow2,if=scsi,id=drive-data-disk,format=qcow2,cache=none,rerror=stop,werror=stop: rerror is not supported by this bus type /etc/qemu-ifdown: could not launch network script Best regards, sluo (In reply to Sibiao Luo from comment #0) > Description of problem: > boot up a guest attaching a data disk speicified if=scsi/ide without > rerror=stop in cli, the QEMU will quit and core dumped. > This bug only hit when specified if=scsi. Please refer to bug 1019538 that if specify if=virtio/ide/floppy. -drive file=/mnt/my-data-disk.qcow2,if=scsi,id=drive-data-disk ... -device scsi-hd,drive=drive-data-disk,id=data-disk,bus=scsi0.0 Notice that an interface is already created with if=scsi, then create another device with the drive, is not a valid use case. Will look into the core dump and replace it with an exit with a friendly error message. |
