Stopping Virtual Machines

To stop one or more virtual machines, perform the following steps. This action allows you to stop the virtual hardware for a virtual machine. When stopped, a virtual machine enters an Off state (powered off) and the virtual machine is halted. Once a virtual machine is stopped, the resources assigned to it no longer are allocated and are now available for use by other virtual machines.




	NOTE: If the OS is running on a virtual machine that you want stopped, HP recommends that you shut down the OS before stopping the virtual machine. This ensures that all applications are shut down cleanly. Virtual machines that are configured as HP Serviceguard packages cannot be stopped by VM Manager. For information about managing virtual machines that are configured as HP Serviceguard packages, see the HP Integrity Virtual Machines Installation, Configuration, and Administration manual.

From the VM Host view, select the VM Host Virtual Machines tab (or any tab that allows you to select one or more virtual machines).
Select one or more virtual machines to stop by clicking the appropriate check boxes.
Alternatively, you can access the VM Properties view, in which case no selection is necessary; the virtual machine being viewed is implicitly selected.
Select ToolsStop Virtual Machine... from the VM Manager menu bar. This displays a page similar to that shown in Figure 4-2.

Figure 4-2 Stop Virtual Machine Page

In the screen example shown in Figure 4-2, two of the selected virtual machines are going to be stopped (bitsy00 and bitsy01), while two are already stopped (vm001 and vms). The screen reports that the OS is running on one of the virtual machines and advises you to shut down the OS on that machine before stopping it.
The How to Stop options allow you to control how a virtual machine is stopped:
- Graceful. This is the default. With a graceful stop, the virtual machine notifies the guest OS of an impending shutdown. This advance notice gives the OS an opportunity to perform cleanup operations before its virtual machine is powered off. A graceful stop typically takes 30 to 60 seconds, but can take as long as 5 minutes because Integrity VM waits for the OS to complete its cleanup operations.
- Forced. A forced stop is the equivalent of a power failure and gives no warning to the guest OS. Because the guest OS receives no advance notice of the power off operation, the OS has no opportunity to perform a crash dump or perform any system cleanup tasks.
If you want to set a forced stop for the machines, click the Forced option; otherwise, skip to the next step.
The Command Preview area shows the commands that Integrity VM will perform to stop the virtual machines.
Click OK to perform the action.
