Abstract
A method for generating and recovering a memory snapshot of a virtual machine is provided. The method includes: obtaining a current Smemory page of the virtual machine; identifying a page type of the current Smemory page, where the page type includes an invalid data page and a valid data page; and recording the page type of the current Smemory page in a memory snapshot file when the page is an invalid data page; and recording the page type and page data of the current Smemory page in the memory snapshot file when the page is a valid data page, so that only valid data is stored according to the embodiments of the present invention, thereby reducing backup of invalid data, greatly shortening the generation time of the memory snapshot, reducing the size of the memory snapshot file, and saving storage resources.
