Suspending a virtual machine is analogous to putting a computer into sleep mode. When a virtual machine is suspended, the current state of the operating system, and applications is saved, and the virtual machine put into a suspended mode. When you resume the virtual machine, the operating system and applications continue from the same point you suspended the virtual machine.
To suspend virtual machines:
Click the Servers and VMs tab.
Select the server pool on which the virtual machine resides in the navigation tree.
Select Virtual Machines from the Perspective drop-down list. Select one or more virtual machines in the management pane, and click Suspend .
The virtual machine state is saved and the virtual machines suspended.
To resume the virtual machine, see Section 3.5.2.10, “Resume Virtual Machine”.
