My local build was successful but let wait for the CI +1.
Problem was caused by the conflict between 2 of my patches:
https://gerrit.ovirt.org/#/c/111119/
and
https://gerrit.ovirt.org/#/c/111471/
Each of them passed the CI test but when applied to master the
conflict occurred.
Sorry for that.
best regards,
