Public bug reported: During migration of an openstack booted instance, I got the following error:
Apr 12 10:55:22 cmp1 libvirtd[4133]: 2018-04-12 10:55:22.133+0000: 4139: error : qemuMonitorJSONCheckError:392 : internal error: unable to execute QEMU command 'drive-mirror': error parsing address 'cmp0 .sandriichenko-deploy-heat-virtual-mcp-pike-ovs-76.bud-mk.local:49153' A bit more info in libvirt bug https://bugzilla.redhat.com/show_bug.cgi?id=1568939 To reproduce it with qemu only, I followed the guide at https://github.com/qemu/qemu/blob/master/docs/interop/live-block- operations.rst#id21. On dest and source compute nodes, I launched an instance: qemu-system-x86_64 -display none -nodefconfig -M q35 -nodefaults -m 512 -blockdev node-name=node-TargetDisk,driver=qcow2,file.driver=file,file .node-name=file,file.filename=./test-instance-mirror.qcow2 -device virtio-blk,drive=node-TargetDisk,id=virtio0 -S -monitor stdio -qmp unix :./qmp-sock,server,nowait -incoming tcp:localhost:6666 Then on dest node I launched nbd server: (qemu) nbd_server_start cmp0:49153 (qemu) nbd_server_add -w node-TargetDisk On the source node: (qemu) drive_mirror -n node-TargetDisk nbd:cmp0.vdrok-deploy-heat-virtual-mcp-pike-ovs-foobarbuzz.bud-mk.local:49153:exportname=node-TargetDisk error parsing address 'cmp0.vdrok-deploy-heat-virtual-mcp-pike-ovs-foobarbuzz.bud-mk.local:49153' When using short host name instead of FQDN address seems to be parsed fine: (qemu) drive_mirror -n node-TargetDisk nbd:cmp0:49153:exportname=node-TargetDisk qcow2 Image is not in qcow2 format (not sure why it is not a qcow2 format, as I have qcow2 image with raw backing file, but this is unrelated) QEMU version is 2.11.1 from bionic ** Affects: qemu (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770417 Title: Qemu can not parse long fqdns during drive-mirror To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1770417/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
