HP Integrity Virtual Server Manager 6.3 User Guide

Once a VM is started, the resources assigned to the VM are allocated for its use. The VSP ensures
that the resources required by the VM are available in the current VSP system environment. If the
VM cannot be started, Integrity Virtual Server Manager displays messages indicating which
resources cannot currently be provided.
For information about possible reasons that a VM might not start, see “Troubleshooting VM or vPar
problems” (page 142).
Stopping VMs
To stop one or more VMs, perform the following steps. This action allows you to stop the virtual
hardware for a VM. When stopped, a VM enters an Off state (powered off) and the VM is halted.
Once a VM is stopped, the resources assigned to it no longer are allocated and are now available
for use by other VMs.
NOTE: If the OS is running on a VM that you want stopped, HP recommends that you shut down
the OS before stopping the VM. This ensures that all applications are shut down cleanly.
You cannot stop a VM that is currently migrating online. You must wait until migration completes.
If the selected VM has migrated to another VSP (the target), the VM (on the source VSP) is in the
Not Runnable state: attempts to stop the VM will fail.
1. From the VSP view, select the VSP Virtual Servers tab (or any tab that allows you to select one
or more VMs).
2. Select one or more VMs to stop by clicking the appropriate check boxes.
Alternatively, you can access the VM Properties view, in which case no selection is necessary;
the VM being viewed is implicitly selected.
3. Select Tools→Stop Virtual Machine... from the Integrity Virtual Server Manager menu bar. This
displays a page similar to that shown in Figure 65.

4. In the screen example shown in Figure 65, one of the selected VMs is going to be stopped
(vm001), while one is already stopped (vm002). The OS is running on one of the VMs and
you have to shut down the OS on that machine before stopping it.
The How to Stop options allow you to control how a VM is stopped:
• Graceful. This is the default. With a graceful stop, the VM notifies the guest OS of an
impending shutdown. This advance notice gives the OS an opportunity to perform cleanup
operations before its VM is powered off. A graceful stop typically takes 30 to 60 seconds,
