Killing a virtual machine is equivalent to performing a power off of a virtual machine, similar to unplugging the power cable from a physical machine. This is not the recommended method of shutting down a virtual machine, but may be used if the shut down command fails to shut down the virtual machine.
To kill 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 Kill .
The virtual machines are powered off.
