Hi,
did you found a solution or cause for this high CPU usage? I have installed the self hosted engine on another server and there is no VM running but ovirt-ha-agent uses heavily the CPU.
Yes, it's due to the fact that ovirt-ha-agent periodically reconnects over json rpc and this is CPU intensive since the client has to parse the yaml API specification each time it connects. The issue is tracked here: https://bugzilla.redhat.com/show_bug.cgi?id=1349829 - ovirt-ha-agent should reuse json-rpc connections but it depends on: https://bugzilla.redhat.com/show_bug.cgi?id=1376843 - [RFE] Implement a keep-alive with reconnect if needed logic for the python jsonrpc client

Does the spikes correlates with info messages on extracting the ovf?
yes, it seems so and it happens every 14-15 seconds....
These are the lines I see scrolling in agent.log when I notice cpu spikes in ovirt-ha-agent...
