Kevin, Thanks for the suggestion of share-rw=on. I figured I'd try to change our 'xkvm' wrapper around qemu to use that.
Unfortunately, it looks like , at least in our version of qemu (QEMU emulator version 2.10.0(Debian 1:2.10+dfsg-0ubuntu1)), that this does not work with the -drive path. $ qemu-img create -f qcow2 disk1.img 1G $ qemu-system-x86_64 \ -device virtio-net-pci,netdev=net00 \ -netdev type=user,id=net00 \ -drive id=drive01,file=disk1.img,format=qcow2,share-rw=on \ -device drive=drive01,serial=sn-drive01,driver=virtio-blk,index=1 \ -device drive=drive01,serial=sn-drive01,driver=virtio-blk,index=2 qemu-system-x86_64: -drive id=drive01,file=disk1.img,format=qcow2,share-rw=on: Block format 'qcow2' does not support the option 'share-rw' I had thought you were suggesting the above, right? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716028 Title: qemu 2.10 locks images with no feature flag To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1716028/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
