3.5.2 VM Guest

The power state of a VM guest can be controlled by clicking the OS icon of its VM host and then clicking its power button in the list of VM guests that is displayed.
Clicking on that power button provides power controls similar to those provided for server blades.

Table 3.16 Actions of VM guest power buttons
Power Button	Color	Current Status	Action
	Gray (no light)	Power OFF	Powers on a VM guest.
	Green (is lit)	Power ON	Shuts down or reboots a VM guest.

Note

VM guests should be properly configured in order to use the shut down or reboot buttons.
Attempting to shut down or reboot a VM guest that wasn't properly configured will result in an error.
Refer to "A.2 Configuration Requirements" of the "ServerView Resource Coordinator VE Setup Guide" for details.
Depending on the server virtualization environment, a VM guest may automatically migrate to another VM host when being shut down. This may cause power control operations to fail and return an error when used on VM guests. Refer to "A.3 Functional Differences between Products" of the "ServerView Resource Coordinator VE Setup Guide" for details.
A VM guest can be configured to automatically start or stop whenever its VM host starts up or shuts down. This can be achieved by setting up the VM guest's startup and shutdown options in the virtualization software used.
Refer to the virtualization software manual for details.
Take care of the following points when shutting down or rebooting a server running a Windows Operating System.
- If Windows is not configured to shut down when the computer's power button is pressed, the power operations in Resource Coordinator VE may not function properly.
  To check this option, open [Control Panel]-[Power Options]. In the [Power Options Properties] dialog, click the [Advanced] tab, and check the action that is set to be performed when the computer's power button is pressed.
- If a file is being edited by a logged-in user, a dialog prompting the user to save the file is displayed, and the system may not shut down immediately.
  In such cases, shutdown does not take place until the user takes the appropriate action or a specified time (approximately five minutes) has elapsed.
