handle_qmp_command was part of the functionality required by the flight recorder. I have sent the following patch upstream: [PATCH 0/2] monitor: add trace events for HMP and QMP commands Once it has been merged I will backport it and the flight recorder will work again. If I understood the problem correctly, this is a regression in the flight recorder feature. Setting keyword, please correct if that's not the case.

You've set it to POST, but I don't see the backport yet, reverting back to ASSIGNED. The backport has been posted. I hope this can still make it into RHEL 7.4.
