【摘要】：近来,快速提高的硬件计算能力与硬件使用效率低的问题引起业界众多的关注,而物理服务器的高价格以及资源占用量大(如空间和电能)等问题,使得虚拟技术越来越受到人们的青睐,在业界各大厂商的大力推动下,虚拟化技术得到了快速的发展。结合行业前沿的云计算,虚拟云计算成为信息技术的一个新焦点。在众多的虚拟化技术应用中,虚拟机监视器占有非常重要的地位。目前较为流行的虚拟机监视器包括VMware、VirtualBox、Xen、KVM等,本文就实现了一个基于Xen虚拟机监视器系统中的远程监控模块。Xen虚拟机监视器是一款开源的虚拟机管理软件,具有良好的体系结构与优越的性能,被业界广泛看好,对Xen下的虚拟机的远程监控是本文的主要讨论对象。本文主要内容如下：本文首先介绍了虚拟技术及Xen的发展,并对项目中涉及的主要技术作一个简要介绍,包括Xen虚拟机监视器、Intel VT技术和Libvirt函数库,并通过引入RemoteXen系统,提出了Xen下虚拟机的远程监控的问题。在此基础上分析了远程监控的目标,提出方案,设计并实现了项目系统中基于Xen虚拟机监视器的远程监控模块。为提高性能,在实现远程监控的同时,需要解决虚拟机对硬件设备(主要是显卡)直接访问的问题。测试表明,通过RemoteXen系统,在一台物理机上只要物理内存允许,可以创建任意多台虚拟机,并且这些虚拟机可以是不同平台的系统。RemoteXen系统同时支持包括Windows7、WindowsXP32位和64位的版本,以及Fedora的32位和64位系统。该系统极大的方便了用户对虚拟机的远程操作,包括虚拟机的远程开启、关闭、克隆,虚拟机之间的切换等,用户只需通过界面点击即可完成操作。最后讨论了一些系统中不足的地方,并对未来的发展作了展望。
[Abstract]:Recently, the problems of fast improving hardware computing power and low efficiency of hardware use have attracted much attention in the industry, while the high price of physical servers and the large amount of resources (such as space and electricity), etc.Virtual technology is becoming more and more popular, and virtualization technology has been developed rapidly.Combined with industry cutting-edge cloud computing, virtual cloud computing has become a new focus of information technology.Virtual machine monitor plays an important role in many virtualization applications.The popular virtual machine monitor includes VMware Virtual Boxer Xen KVM and so on. This paper implements a remote monitor module based on Xen virtual machine monitor system. Xen virtual machine monitor is an open source virtual machine management software.With good architecture and superior performance, it has been widely considered by the industry. Remote monitoring of virtual machines under Xen is the main object of discussion in this paper.The main contents of this paper are as follows:This paper first introduces the development of virtual technology and Xen, and gives a brief introduction to the main technologies involved in the project, including Xen virtual machine monitor, Intel VT technology and Libvirt function library, and introduces RemoteXen system.This paper puts forward the problem of remote monitoring of virtual machine in Xen.On this basis, the paper analyzes the target of remote monitoring, proposes a scheme, and designs and implements the remote monitoring module based on Xen virtual machine monitor in the project system.In order to improve performance, it is necessary to solve the problem of direct access to hardware devices (mainly graphics cards) by virtual machines while implementing remote monitoring.Tests show that with RemoteXen, any number of virtual machines can be created on a physical machine if physical memory permits, and that these virtual machines can be systems with different platforms. RemoteXen systems support both Windows 7N Windows XP 32-bit and 64-bit versions.And Fedora 32-bit and 64-bit system.The system greatly facilitates the remote operation of the virtual machine, including the remote opening, closing, cloning, switching between the virtual machine, and so on. The user only need to click the interface to complete the operation.Finally, some deficiencies in the system are discussed, and the future development is prospected.
