Hypervisor VM有什么好处? [英] What are the benefits of a Hypervisor VM?
问题描述
我正在考虑使用虚拟机来托管多个操作系统，并且正在寻找免费解决方案，其中有很多.我对管理程序是什么以及为什么它们与标准"虚拟机不同或更好感到困惑.当我说标准时，我将使用基准虚拟机VMWare Server 2.0.
I'm looking into using virtual machines to host multiple OSes and I'm looking at the free solutions which there are a lot of them. I'm confused by what a hypervisor is and why are they different or better than a "standard" virtual machine. When I mean standard I going to use the benchmark virtual machine VMWare Server 2.0.
对于具有4 GB内存的双核系统，该系统最多可以运行3个VM.哪个是最佳选择?系统管理程序或非系统管理程序，为什么?我已经阅读了Wikipedia文章，但是技术细节超出了我的脑海.我需要一个基本的答案，这些不同的VM风格可以为我做什么.
For a dual core system with 4 GB of ram that would be capable of running a max of 3 VMs. Which is the best choice? Hypervisor or non-hypervisor and why? I've already read the Wikipedia article but the technical details are over my head. I need a basic answer of what can these different VM flavors do for me.
我的主要问题与如何在多个环境中进行测试有关.我担心操作系统的隔离性，因此可以同时在多个操作系统上测试应用程序.还有哪种风味可以让您更深入地了解真实机器的运行方式?
我正在考虑以下内容:
(管理程序)
- Xen
- Hyper-V
(非管理程序)
- VirtualBox
- VMWare Server 2.0
- Virtual PC 2007
*我列出的VM的分类可能不正确.
*The classifications of the VMs I've listed may be incorrect.
推荐答案
主要区别在于Hyper-V不在操作系统之上运行，而是与系统一起在称为管理程序的薄层之上运行. Hypervisor是一种计算机硬件平台虚拟化软件，它允许多个操作系统同时在主机上运行.
The main difference is that Hyper-V doesn't run on top of the OS but instead along with the system it runs on top of a thin layer called hypervisor. Hypervisor is a computer hardware platform virtualization software that allows multiple operating systems to run on a host computer concurrently.
许多其他虚拟化解决方案使用诸如仿真之类的其他技术.有关更多详细信息，请参见维基百科.
Many other virtualization solution uses other techniques like emulation. For more details see Wikipedia.
