Abstract
A computer-implemented method, apparatus, and virtual machine for facilitating the communication between VMs. The method of facilitating the communication between a first VM and a second VM includes: allocating a shared memory segment from within the memory of the physical machine; mapping the requested memory space addresses to the shared memory segments in response to the memory space requests from the VMs; and providing the requested memory space addresses. A method of communication from a first VM to a second VM includes: requesting a memory space in response to a notification that a shared memory segment has been allocated; obtaining the requested memory space address, which has been mapped to the allocated shared memory segment; and accessing communication data in the shared memory segment according to the address. The apparatus and virtual machine executes the steps of the methods.
