[pve-devel] [PATCH qemu-server v6 10/10] migrate: add transfer summary

[Dominik Csapak]

showing a final transfer log line helps with identifying what was
actually transferred. E.g. it could happen that the VFIO state was only
transferred in the last iteration. In such a case we would not see that
information at all.
