基于虚拟化技术的客户虚拟机内核模块检测方法

摘要

虚拟化技术是云计算的关键技术之一.同时，监视虚拟机又是虚拟化平台的一个重要功能.为了更好的获取客户虚拟机的内部信息，在Xen虚拟化环境中设计并实现了一种轻量级的虚拟机内核模块检测方法KMDM. KMDM驻留在宿主机里面，利用虚拟机自省机制来获取被监控虚拟机的内核模块信息.实验结果表明， KMDM能够全面检测客户虚拟机的内核模块信息，检测结果准确、可靠.%The virtualization technology is one of the key technologies of the cloud computing. Meanwhile, monitoring virtual machine is an important function on the virtualization platform. In order to obtain the internal information of the virtual machine better, a lightweight virtual machine kernel module detection method (KMDM) is designed and implemented on the virtualization environment of Xen. The KMDM resides in the host machine and uses the virtual machine introspection mechanism to obtain the kernel module information of the virtual machine. The experimental results show that the KMDM can detect the kernel module information of the guest virtual machine, and the detection results are accurate and reliable.
