Starting a virtual machine starts the virtual hardware for the virtual machine. The virtual machine enters an On state (powered on).

The Start and Restart functions are similar except the Start function does not stop and restart a virtual machine that is already started (it leaves the started machine as is), while the Restart function does. Use Restart instead of Start when you have several virtual machines that you want newly started, some which are already started and some currently stopped. The Restart function takes care of all the virtual machines (in contrast, the Start function does not restart the already started machines). If you do not want the already started machines stopped and restarted (you just want the stopped machines started), use the Start function instead. For information about restarting virtual machines, see “Restarting Virtual Machines”.

NOTE: Virtual machines that are configured as HP Serviceguard packages cannot be started 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.

To start one or more selected virtual machines, perform the following steps.

  1. From the VM Host General tab, select the VM Host Virtual Machines tab (or any tab that allows you to select one or more virtual machines).

  2. Select one or more virtual machines to start 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.

  3. Select Tools->Start Virtual Machine... from the VM Manager menu bar. A page similar to that shown in Figure 4-1 is displayed.

  1. In the example shown in Figure 4-1, two virtual machines will be started. A note near the bottom of the screen indicates that two of the selected virtual machines are already started. The Command Preview area shows the commands that Integrity VM will perform to start the virtual machine.

    Click OK to start the virtual machine.

When a virtual machine is started, it is in the On state (powered on). You can then perform the functions you want.

NOTE: Depending on the settings in the virtual machine's Extensible Firmware Interface (EFI), starting a virtual machine might not boot the operating system. For more information, see “Creating Virtual Machines”.

Once a virtual machine is started, the resources assigned to the virtual machine are allocated for its use. The VM Host ensures that the resources required by the virtual machine are available in the current VM Host system environment. If the virtual machine cannot be started, VM Manager displays messages indicating which resources cannot currently be provided.

For information about possible reasons that a virtual machine might not start, see “Troubleshooting Virtual Machine Problems”.
