Description Leonid Natapov 2013-10-01 08:38:15 EDT
Missing parameter to log message which is printed when a vm needs to be migrated to a better host caused failure in second host's ON state, causing a) metadata to not be updated, b) vm to not be migrated, c) first host to think second host died, d) first host to try and start vm.

agent.log output:
': 'purple-vds3.qa.lab.tlv.redhat.com', 'alive': True, 'engine-status': 'vm-up good-health-status', 'score': 1000, 'first-update': False}

Patch merged upstream master
Comment 2 Leonid Natapov 2013-10-02 07:33:59 EDT
Instructions for QA:
Check that engine vm migration works e.g. when engine vm dies on on host it starts on t he second. Check that there is no "TypeError: not enough arguments for format string" error in agent.log file.
