Somehow libvirt (virsh) is not checking the block-job execution: <while the first "virsh blockcommit" is stuck, I can do this...>
inaddy@(kvm02):~$ virsh qemu-monitor-command guest --pretty -- '{ "execute": "query-block-jobs" }' { "return": [ { "io-status": "ok", "device": "drive-virtio-disk0", "busy": false, "len": 32212254720, "offset": 32212254720, "paused": false, "speed": 0, "type": "commit" } ], "id": "libvirt-511" } inaddy@(kvm02):~$ virsh blockjob guest /var/lib/libvirt/images/guest.1487158333 Block Commit: [100 %] With "query-block-jobs" you can see if it finished (offset - len = 0). Virsh is not doing this, so I have to finish the job by hand: inaddy@(kvm02):~$ virsh qemu-monitor-command guest --pretty -- '{ "execute": "block-job-complete", "arguments": { "device": "drive-virtio-disk0" } }' { "return": { }, "id": "libvirt-859" } And the command returns: inaddy@(kvm02):~$ virsh blockcommit --domain guest vda --base /var/lib/libvirt/images/guest.qcow2 --top /var/lib/libvirt/images/guest.1487158333 --wait --verbose Block Commit: [100 %] Commit complete Problem is that QEMU has the correct answer for the backing file: inaddy@(kvm02):~$ virsh qemu-monitor-command guest --pretty -- '{ "execute": "query-block" }' { "return": [ { "io-status": "ok", "device": "drive-virtio-disk0", "locked": false, "removable": false, "inserted": { "iops_rd": 0, "image": { "virtual-size": 32212254720, "filename": "/var/lib/libvirt/images/guest.qcow2", "cluster-size": 65536, "format": "qcow2", "actual-size": 5328867328, "format-specific": { "type": "qcow2", "data": { "compat": "1.1", "lazy-refcounts": false } }, "dirty-flag": false }, "iops_wr": 0, "ro": false, "backing_file_depth": 0, "drv": "qcow2", "iops": 0, "bps_wr": 0, "encrypted": false, "bps": 0, "bps_rd": 0, "file": "/var/lib/libvirt/images/guest.qcow2", "encryption_key_missing": false }, "type": "unknown" }, { "io-status": "ok", "device": "drive-ide0-0-0", "locked": false, "removable": true, "tray_open": false, "type": "unknown" } ], "id": "libvirt-861" } But libvirt still thinks its using the old un-merged snapshot: inaddy@(kvm02):~$ virsh domblklist --domain guest Target Source ------------------------------------------------ vda /var/lib/libvirt/images/guest.1487158333 hda - Will work on libvirt to fix this.... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1317491 Title: virsh blockcommit hangs at 100% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1317491/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
