If you want to change a virtual machine's name, resource group or whether it is highly available, you can do this as needed.
From the "Virtual Machines" browser view, click on to bring up the change dialog box.
From your virtual machine's details view, click on the "Edit Settings" button to bring up the change dialog box.
Enter your new settings for "Name", "Resource Group" and whether or not you want this machine to be highly available. When done, click on the"Update Virtual Machine" button to save your changes.
Note: High availability determines whether a virtual machine is automatically restarted when it is shut down for an unknown reason. If high availability is enabled and the virtual machine is manually shut it down within a terminal session, the machine will automatically be restarted by Stratosphere. However, if you click on the "Stop" button on the Stratosphere portal interface, the machine will remain shut down. This will also apply to API calls using the stopVirtualMachine command.
The high availability setting can be set on a per machine basis.
