Development of Novel Applications of Hypervisors

我们开发了虚拟机监控程序的新应用程序。我们已经确定了几个基于虚拟机管理程序的系统，它们不一定在世界上广泛使用，但可能很有用。我们开发的第一个应用程序是在虚拟机的桌面屏幕上显示消息。我们修改后的虚拟机管理程序操纵图形硬件的帧缓冲区，从而在屏幕上显示图像。第二个应用是保护程序代码中包含的知识产权。应用程序将操作系统内核的代码分为公开部分和秘密部分。公共部分分发给虚拟机的用户并在虚拟机中执行。秘密部分对虚拟机的用户是隐藏的，并由管理程序执行。我们还探索了将虚拟机监控程序应用于云计算和恶意软件检测领域。

We have developed novel applications of hypervisors. We have identified several hypervisor-based systems that are not necessarily widespread in the world but are potentially useful. The first application we develop is to display messages on a desktop screen of a virtual machine. Our modified hypervisor manipulates the frame buffer of graphics hardware and thus displays images on the screen. The second application is to protect the intellectual properties included in program code. The application divides the code of an operating system kernel into a public part and a secret part. The public part is distributed to the users of a virtual machine and executed in the virtual machine. The secret part is hidden from the users of the virtual machine and executed by the hypervisor. We have also explored to apply hypervisors to the fields of cloud computing and malware detection.
