If all hosts supports mailbox events, the SPM does not need to read the mailbox
every 2 seconds, minimizing I/O and CPU usage on the SPM host.

Hosts report new capability:

"mailbox_events": true

If all hosts report this capability, engine can configure the SPM to use only mailbox events.

Requires a change in vdsm and engine.

Plan:

  • Disable periodic checking of the mailbox
  • Measure I/O and CPU usage with and without mailbox checking on real server
  • Prioritize this issue base on the result.
