This is actually expected because there's no way the source libvirtd could send the statistics to the destination libvirtd once migration is complete. The statistics are sent when the destination libvirtd is asked to start the newly migrated domain, but the source libvirtd keeps measuring the total time until it kills the domain on the source host. |
Description of problem: "domjobinfo --complete" displays different time elapsed and time elapsed w/o after migration. This issue should be a regression. It does not exist on libvirt-1.3.2-1.el7.x86_64. Version-Release number of selected component (if applicable): libvirt-1.3.3-1.el7.x86_64 qemu-kvm-rhev-2.5.0-4.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. Setup nfs on both hosts. On remote host: # df -k 10.66.5.225:/usr/share/avocado/data/avocado-vt/images 52403200 33089536 19313664 64% /var/lib/libvirt/migrate Guest XML: <devices> ... <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='none'/> <source file='/var/lib/libvirt/migrate/jeos-21-64.qcow2'/> <target dev='vda' bus='virtio'/> ... </disk> 2. Run migration command: virsh migrate avocado-vt-vm-ci --live --verbose --unsafe qemu+ssh://10.66.4.167:22/system Migration: [100 %] Migration succeeds. 3. On the local host, run domjobinfo: /bin/virsh domjobinfo avocado-vt-vm-ci --completed Job type: Completed Time elapsed: 2950 ms Time elapsed w/o network: 2945 ms Data processed: 231.416 MiB Data remaining: 0.000 B Data total: 1.016 GiB Memory processed: 231.416 MiB Memory remaining: 0.000 B Memory total: 1.016 GiB Memory bandwidth: 93.107 MiB/s Dirty rate: 0 pages/s Iteration: 4 Constant pages: 209288 Normal pages: 58668 Normal data: 229.172 MiB Total downtime: 118 ms Downtime w/o network: 113 ms Setup time: 8 ms 4. On the remote host run domjobinfo: # /bin/virsh domjobinfo avocado-vt-vm-ci --completed Job type: Completed Time elapsed: 2949 ms Time elapsed w/o network: 2944 ms Data processed: 231.416 MiB Data remaining: 0.000 B Data total: 1.016 GiB Memory processed: 231.416 MiB Memory remaining: 0.000 B Memory total: 1.016 GiB Memory bandwidth: 93.107 MiB/s Dirty rate: 0 pages/s Iteration: 4 Constant pages: 209288 Normal pages: 58668 Normal data: 229.172 MiB Total downtime: 118 ms Downtime w/o network: 113 ms Setup time: 8 ms Actual results: "Time elapsed" and "Time elapsed w/o network" are different on both hosts. Expected results: They should be equal. Additional info:
