Github user koushik-das commented on the pull request: https://github.com/apache/cloudstack/pull/741#issuecomment-134895552 @miguelaferreira For running tests using simulator follow this https://cwiki.apache.org/confluence/display/CLOUDSTACK/Validating+check-ins+for+your+local+changes,+using+Simulator. The tests in smoke/test_scale_vm.py needs real hardware (as there is some SSH being done to the VM created) and so cannot be run with simulator. But you can manually run a scenario where you scale up a running VM in simulator environment. About the commit message, the header does say that the commit is about simulator fixes. Since there are other changes as well, I didn't mention in the header that the commit is only about scale VM support.
