Github user koushik-das commented on the pull request: https://github.com/apache/cloudstack/pull/656#issuecomment-129300344 @remibergsma Thanks for testing the PR. This is a best-effort fix. The change just schedules the restart of the system VMs ahead of the user VMs. Now if there are fewer VMs for restart, there is a higher probability of all restart jobs getting executed at the same time by the HA-worker thread pool. In this case the fix won't be effective. If there are more VMs then the effectiveness of the fix increases.
