Your example does work (using -blockdev), but I can't get it to work with -drive.
$ qemu-system-x86_64 \ -drive id=d01,file=disk1.img,format=qcow2 \ -device drive=d01,serial=s01,driver=virtio-blk,index=1,share-rw=on \ -device drive=d01,serial=s01,driver=virtio-blk,index=2,share-rw=on warning: TCG doesn't support requested feature: CPUID.01H:ECX.vmx [bit 5] qemu-system-x86_64: -device drive=d01,serial=s01,driver=virtio-blk,index=1,share-rw=on: Drive 'd01' is already in use because it has been automatically connected to another device (did you need 'if=none' in the drive options?) ## ok, fix that error, add 'if=none' to the -drive. $ qemu-system-x86_64 \ -drive id=d01,file=disk1.img,format=qcow2,if=none \ -device virtio-blk,drive=d01,serial=s01,index=1,share-rw=on \ -device virtio-blk,drive=d01,serial=s01,index=2,share-rw=on qemu-system-x86_64: -device drive=d01,serial=s01,driver=virtio-blk,index=1,share-rw=on: Property '.index' not found ## ok, index belongs on the -drive (which I should have known from ## the past, but which seems not the right place). Try that anyway. $ qemu-system-x86_64 \ -drive id=d01,file=disk1.img,format=qcow2,if=none,index=1 \ -device virtio-blk,drive=d01,serial=s01,share-rw=on \ -device virtio-blk,drive=d01,serial=s01,share-rw=on qemu-system-x86_64: -device drive=d01,serial=s01,driver=virtio-blk,share-rw=on: Drive 'd01' is already in use by another device ## Huh? Isn't that what I said to explicitly allow with share-rw=on? Note that I've also tried with 'format=raw'. Is there something I'm missing to try to use -drive and -device ? Lastly (if you're still reading), how do you specify the format of the file to -blockdev ? adding 'format=qcow2' makes qemu complain that "'format' is unexpected".
