host info:
# uname -r && rpm -q qemu-kvm
3.10.0-3.el7.x86_64

e.g:...-drive file=/home/vmdk-data-disk.vmdk,if=none,id=drive-data-disk,format=vmdk,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,bus=pci.0,addr=0x7,drive=drive-data-disk,id=data-disk
qemu-kvm: -drive file=/home/vmdk-data-disk.vmdk,if=none,id=drive-data-disk,format=vmdk,cache=none,werror=stop,rerror=stop: 'vmdk' invalid format
/etc/qemu-ifdown: could not launch network script

Retried it with the latest qemu-kvm version that it will give a message prompt "vmdk: Operation not supported". But still not as expected, you should refer to bug 999788#c7 that should give message prompt like: vmdk' can be only used as read-only device.

host info:
3.10.0-41.el7.x86_64
qemu-kvm-1.5.3-13.el7.x86_64

e.g:...-drive file=/home/vmdk-data-disk.vmdk,if=none,id=drive-data-disk,format=vmdk,cache=none,werror=stop,rerror=stop -device virtio-blk-pci,bus=pci.0,addr=0x7,drive=drive-data-disk,id=data-disk -vnc :1 -monitor stdio
qemu-kvm: -drive file=/home/vmdk-data-disk.vmdk,if=none,id=drive-data-disk,format=vmdk,cache=none,werror=stop,rerror=stop: could not open disk image /home/vmdk-data-disk.vmdk: Operation not supported

Comment 4 Fam Zheng 2014-04-18 06:33:45 UTC

Upstream 2.0 has the following message:

qemu-system-x86_64: -drive file=/stor/image/turnkey-moinmoin-12.0-squeeze-x86.vmdk,if=none,id=drive-data-disk,format=vmdk,cache=none,werror=stop,rerror=stop: could not open disk image /stor/image/turnkey-moinmoin-12.0-squeeze-x86.vmdk: Driver 'vmdk' can only be used for read-only devices

Moving to POST and waiting for rebase.
