Embodiments of the present disclosure relate to a method, an electronic device, and a computer program product for controlling a virtual machine. The method comprises: determining external information related to the running of the virtual machine, the external information indicating a first period to be occupied by the virtual machine to process data in association with another virtual machine; determining internal information related to the running of the virtual machine, the internal information indicating a second period to be occupied by the virtual machine to process internally stored data; determining a stop period of the virtual machine based on the external information and the internal information; and controlling the virtual machine to stop running during the stop period. Using the technical solution of the present disclosure, it is possible to intelligently reduce the unnecessary running time of a virtual data protection and storage apparatus in a cloud environment, and thus minimize the running cost of the virtual data protection and storage apparatus itself, which not only can reduce the user cost but also can improve the user experience.
