Barak suggested to just exclude the journal:
https://gerrit.ovirt.org/#/c/95850/
This is fixed now, thanks!
Any reason why we exclude journal only for /var/log, and do collect the
binary journal
from /var/host_log? I guess it can fail in the same way.
If we collect logs for integration tests, the most important log is the
journal, and now
we skip it.
We can get the journal in a reliable way like this:
journalctl --since build-date > /tmp/journal.log
