The embodiment of the invention provides a virtual machine waking method and a virtual machine waking device. The virtual machine waking method comprises the steps of: recovering context information and key internal storage pages into an internal storage to wake a virtual machine by obtaining the context information and the key internal storage pages of the virtual machine, and thereby completing the waking process of the virtual machine; during the process, as the context information and the key internal storage pages of the virtual machine are recovered into the internal storage, so that quantity of data recovered from a disk to the internal storage is reduced to a certain degree, waking speed of the virtual machine is sped up; during the process, additionally deployed components with high cost are not needed, and thereby deployment cost is saved.
