1. Why?

The virtual machine manager application virt-manager does not (currently) have the option to wake a VM from Sleep. In other words, as a VM cannot be awaken by an input device, unfortunately. For example, a physical or virtual "power on", button, keyboard input, or network activity. This application includes the ability to wake from Sleep and Hibernation, and the other related features from virt-manager.
