An I/O optimizing approach for virtualization-based Internetwares

Abstract

Virtualization is a very popular support environment for Internetware deployment. However, the virtual machine can access the hardware only by virtue of virtual machine monitor which can result in a big overhead, especially for I/O sensitive virtual machine. In order to reduce this kind of overhead, this paper gives a research on I/O virtualization and proposes a cache mechanism. In benefit of the cache mechanism build in virtual machine monitor, the data package switching operations would drop dramatically and the overhead is lowered too. It is proved that our method is efficient and effective in decreasing the Internetware I/O overhead in virtualization environment through the experiment.
