The embodiment of the invention provides a virtual machine communication method and device based on a shared memory, and the method comprises the steps that a switch receives a reading request sent bya first virtual machine, the reading request comprises a first local address, and the switch converts the first local address into a first global address according to the mapping relation between thefirst local address and the first global address, wherein the first global address is an address determined according to a first shared memory, and the first shared memory is a part of the memory ofthe switch; the switch converts the first global address into a first physical address according to the mapping relation between the first global address and the first physical address, and the firstphysical address is the physical address of the first shared memory; the switch reads data from the first shared memory according to the first physical address, and the data is written into the firstshared memory by the second virtual machine; and the switch sends the data to the first virtual machine. According to the embodiment, the time delay of reading and writing data from the shared memoryby the virtual machine can be reduced, and the data transmission efficiency is improved.
Description
technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a virtual machine communication method and device based on shared memory. Background technique [0002] With the continuous development of information technology, virtual machine technology has been widely used. A virtual machine (Virtual Machine) refers to a complete computer system that is simulated by software, has complete hardware functions, and runs in a completely isolated environment. Through virtual machine software, one or more virtual computers can be simulated on a physical machine. [0003] In a cloud computing system, not only multiple virtual machines simulated on one physical computer can communicate, but also virtual machines simulated on different physical machines can communicate. Multiple virtual machines can communicate through shared memory. For example, the memory of a virtual machine is used as a shared memory, and othe...
