Subject [jira] [Reopened] (CLOUDSTACK-2567) NPE when scaling of VM on unsupported hypervisor
Date Wed, 22 May 2013 06:05:20 GMT

     [ https://issues.apache.org/jira/browse/CLOUDSTACK-2567?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Prasanna Santhanam reopened CLOUDSTACK-2567:
--------------------------------------------


The logic is reverse handled. The message should print in the else block when scaling is disallowed?

+            // If DMC is not enable then dont execute this command.
+            if (isDmcEnabled(conn, host)) {
+                String msg = "Unable to scale the vm: " + vmName + " as DMC - Dynamic memory
control is not enabled for the XenServer:" + _host.uuid + " ,check your license and hypervisor
version.";
+                s_logger.info(msg);
+                return new ScaleVmAnswer(cmd, false, msg);
+            }
