Anyway we have disabled migration when VMDK images are used, then do live migration with used VMDK format disk should fail with a friendly message prompt. Best Regards, sluo BTW, also tried the rhel7.0 host with the same testing as comment #0 which did not hit this issue, it disable live migration with message prompt, like: (qemu) migrate -d tcp:0:5888 migrate: Block format 'vmdk' used by device 'drive-data-disk' does not support feature 'live migration' host info: 3.10.0-3.el7.x86_64 qemu-kvm-1.5.2-4.el7.x86_64 Best Regards, sluo Verify this issue on qemu-kvm-0.12.1.2-2.410.el6.x86_64 with the steps as comment#0. host info: # uname -r && rpm -q qemu-kvm 2.6.32-420.el6.x86_64 qemu-kvm-0.12.1.2-2.410.el6.x86_64 Steps: the same to comment #0 Results: fail to do migration with used vmdk disk correctly with prompt message that "Block format 'vmdk' used by device 'drive-data-disk' does not support feature 'live migration'". e.g:...-drive file=/mnt/my-data-disk.vmdk,if=none,id=drive-data-disk,format=vmdk,cache=none,werror=stop,rerror=stop,readonly=on -device virtio-blk-pci,bus=pci.0,addr=0x7,drive=drive-data-disk,id=data-disk (qemu) migrate -d tcp:0:5888 Block format 'vmdk' used by device 'drive-data-disk' does not support feature 'live migration' (qemu) info migrate (qemu) info status VM status: running Base on above, this issue has been fixe correctly, move to VERIFIED status, please correct me if any mistake.
