HP Integrity Virtual Machines Manager 4.1 Software: User Guide

Figure 6-2 Stop Virtual Machine page
4. In the screen example shown in Figure 6-2, 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.
5. The Command Preview area shows the commands that Integrity VM will perform to stop
the virtual machines.
Click OK to perform the action.
