Virtual machines have a guest operating system on which you can install and run any software supported by that operating system. In vCloud Director, you can install VMware Tools, insert DVDs and floppy disks, and remotely connect to virtual machines.
These are the most basic operations that you can do on a virtual machine.
Power On, which is equal to powering on a physical machine.
Power Off, which is equal to powering off a physical machine.
Suspend, where the CPU of a deployed virtual machine is frozen. You can suspend a machine when you need to leave a virtual machine but do not want to lose its current state.
Reset, which power cycles the virtual machine.
