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
cheers
