BTW to reduce the scope what to think about - I have rebuilt 6.8 as
well it works.
Thereby I can confirm that the offending change should be in between
6.8.0 -> 6.9.0.

One very important part of '--tunnelled' migration is the use of
virStream APIs to transport the migration data. Perhaps something there
is broken since it doesn't reproduce when not using the tunnel
Thanks for the hint Peter.
I was now looking there as well, but other than the switch to g_new0
there is neither a change carrying the words "stream" nor one that
is affecting the related files that implement virStream*.
