Description of problem: If one or more hosts were recently in cpu overcommit state, the inventory script will fail with: # /usr/share/ovirt-engine/setup/bin/ovirt-engine-hosts-ansible-inventory Traceback (most recent call last): File "/usr/share/ovirt-engine/setup/bin/ovirt-engine-hosts-ansible-inventory", line 223, in <module> main() File "/usr/share/ovirt-engine/setup/bin/ovirt-engine-hosts-ansible-inventory", line 217, in main indent=(4 if args.pretty else None), File "/usr/lib64/python2.7/json/__init__.py", line 243, in dumps return _default_encoder.encode(obj) File "/usr/lib64/python2.7/json/encoder.py", line 207, in encode chunks = self.iterencode(o, _one_shot=True) File "/usr/lib64/python2.7/json/encoder.py", line 270, in iterencode return _iterencode(o, 0) File "/usr/lib64/python2.7/json/encoder.py", line 184, in default raise TypeError(repr(o) + " is not JSON serializable") TypeError: datetime.datetime(2017, 1, 24, 23, 41, 24, 317019, tzinfo=psycopg2.tz.FixedOffsetTimezone(offset=120, name=None)) is not JSON serializable This specifically happens when the column cpu_over_commit_time_stamp in the table vds_statistics is not empty for one or more rows. Version-Release number of selected component (if applicable): current master/4.1 How reproducible: Always Steps to Reproduce: 1. See above 2. 3. Actual results: Fails Expected results: Succeeds. Still not sure what should be put in that field, but it does not seem very important for the scope of this script. Additional info: A workaround is to get out of this state, by lowering the load on all hosts (e.g. by adding a host and migrating some VMs, or by stopping VMs) and then waiting a bit until the engine updates this column.
