Abstract
The present invention provides a method and apparatus for data swap in a virtual machine environment. The present invention provides a method for data swap in a virtual machine environment, including: in response to a swap request from a virtual machine, looking up storage space associated with the swap request; and allocating to the virtual machine free physical storage space, in a host, which matches the storage space, so that the free physical storage space logically becomes available storage space to the virtual machine; the virtual machine is running on the host, and the storage space is physical storage space in the host.
