CAUTION During the undeploy operation, an orderly shutdown of the virtual machines does not exist. The undeploy operation "turns off" the virtual machines before uninstantiating them, and removes them from the Managed Server pool. For example, if you have an application open on a Windows virtual machine, you must remember to save your work. If you need to preserve the current state of the configuration, capture the configuration to the configuration library. „ Turn Off - Turns off all virtual machines in the configuration. Turning off a virtual machine is the virtual equivalent of powering down a physical machine. The configuration remains registered on the Managed Server pool. The Turn On option reverses this operation. „ Suspend - Suspends CPUs for all the virtual machines. The configuration remains registered on the Managed Server pool. The Resume option reverses this operation. Cloning Configurations You can clone your own configuration or configurations shared by other users. A cloning operation creates a delta disk instead of copying an entire virtual hard disk. This operation addresses virtual machine proliferation by using "referential provisioning," a process that involves storing new changes but referring back to a chain of delta disks. For each change, Lab Manager freezes the original delta disk and creates a new one. When you clone a configuration, Lab Manager assigns the same network parameters to the cloned virtual machines. If you deploy the original and cloned configurations at the VMware, Inc. 91
