Extending Hypervisor Architecture to Allow OneWay Data Transfers from VMs to Hypervisors

摘要

We propose an alternative architecture to existing hypervisors, which allows for more data to be moved whilst requiring less work for hardware and networks. Our suggestion is to develop an extension to hypervisors for an interface which can allow data transfer one way from virtual machines to hypervisors. We argue that the ability to transfer data directly in this way can provide a number of benefits to cloud users and providers, namely in the areas of security (confidentiality, integrity, and through decreased overhead), reduced energy consumption, and better use of hardware resources.
