Research on Xen Inter Domain Communication Based on Shared Memory

When the virtual machine technique is applied to many fields such as the server integration,the communication inter virtual machines will be very complex and frequent,and so the communication mechanism of the virtual machines themselves will become a bottleneck.Currently,when one guest virtual machine in Xen wants to communicate with another on the same physical machine,it must extend the data transfer path and degrade the inter-domain communication performance.On the basis of an intensive study of the communication of the Xen virtual machines,it puts forward a communicating method based on the shared memory,which is used to improve the performance of the communication between different virtual machines on one physical machine.The experimental result shows that this method has greatly increased the communication bandwidth between virtual machines,and effectively balanced the CPU utilization of every virtual machine as well.
