Fixes already in build, patch not properly updated. Verified this issue with qemu-kvm-rhev-0.12.1.2-2.431.el6.x86_64. host info: # uname -r && rpm -q qemu-kvm-rhev 2.6.32-492.el6.x86_64 qemu-kvm-rhev-0.12.1.2-2.431.el6.x86_64 #### scenarios 1. Use qemu-img to create and read the vpc/vhdx image correctly, and then attach it in KVM as a second disk specified readonly=on. 1.Use qemu-img to create and read the vpc/vhdx image. # qemu-img create -f vpc my-data-disk.vpc 10G Formatting 'my-data-disk.vpc', fmt=vpc size=10737418240 # qemu-img info my-data-disk.vpc image: my-data-disk.vpc file format: vpc virtual size: 10G (10737893376 bytes) disk size: 24K cluster_size: 2097152 # qemu-img create -f vhdx my-data-disk.vhdx 10G Formatting 'my-data-disk.vhdx', fmt=vhdx size=10737418240 log_size=1048576 block_size=0 block_state_zero=off # qemu-img info my-data-disk.vhdx image: my-data-disk.vhdx file format: vhdx virtual size: 10G (10737418240 bytes) disk size: 272K cluster_size: 16777216 2.using QEMU, launch a guest with the VHDX data disk as a secondary disk. e.g:...-drive file=/home/my-data-disk.vhdx,if=none,format=vhdx,id=drive-data-disk,cache=none,werror=stop,rerror=stop,readonly=on -device virtio-blk-pci,bus=pci.0,addr=0x7,drive=drive-data-disk,id=data-disk Results: after step 1, use qemu-img to create and read the vpc/vhdx image successfully. after step 2, using QEMU to launch a guest with the VHDX data disk as a secondary disk(readonly) successfully. #### scenarios 2. Use Hyper-V to install OS and generate an image(clean dynamic & fixed image files), then convert it to qcow2/raw format via qemu-img and boot it in KVM environment. 1.Use Hyper-V to install OS and generate an image(clean dynamic & fixed image files). 2.convert it to qcow2/raw format via qemu-img. # qemu-img convert -p -f vhdx RHEL-7.0.z-Server-x86_64.vhdx -O qcow2 RHEL-7.0.z-Server-x86_64.qcow2 (100.00/100%) 3.boot it in KVM with simulate driver. e.g:# /usr/libexec/qemu-kvm -M pc -cpu Opteron_G2 -enable-kvm -m 2048 -smp 2,sockets=2,cores=1,threads=1 -no-kvm-pit-reinjection -usb -device usb-tablet,id=input0 -name sluo -uuid 990ea161-6b67-47b2-b803-19fb01d30d30 -rtc base=localtime,clock=host,driftfix=slew -drive file=/home/RHEL-7.0.z-Server-x86_64.qcow2,if=none,id=drive-system-disk,format=qcow2,cache=none,aio=native -device ide-drive,drive=drive-system-disk,id=system-disk,bus=ide.0,unit=0 -k en-us -boot menu=on -qmp tcp:0:4444,server,nowait -serial unix:/tmp/ttyS0,server,nowait -vnc :1 -spice disable-ticketing,port=5931 -monitor stdio 4.reboot/shutdown/poweroff guest. Results: after step 2, it convert successfully. after step 3, boot up in KVM successfully. after step 4, reboot/shutdown/poweroff VM successfully. Base on above, this issue has been fixed correctly, move to VERIFIED status, please correct me if any mistake.
