Suspending a virtual machine is similar to putting a real computer into the sleep mode. When you suspend a virtual machine, you save its current state (including the state of all applications and processes running in the virtual machine) to a special file on your. When the suspended virtual machine is resumed, it continues operating at the same point the virtual machine was at the time of its suspending.
Suspending your virtual machine may prove efficient if you need to restart your host, but do not want to:
- Quit the applications running in the virtual machine
- Spend much time on shutting the guest operating system down and then starting it again
