This article shows you how to analyze Win server 2008 virtualized applications. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

As a new highlight of Windows server 2008, Hyper-V is concerned by more and more people, because it can meet the needs of people to run many services on a physical server, which is far greater than the function provided by a server. No more hardware equipment is needed to achieve the transition from a single server to a multi-function server, which is what every unit manager would like to see most, and all the work can be done by setting up a Hyper-V server.

First, the particularity of the location determines the improvement of performance.

The construction structure of the virtual software we used in the past, such as VirtualBox and Virtual PC, is different from that of Hyper-V, except that the former is from low to high to hardware-> OS- > virtualization software-> virtual machine. The data on the virtual machine needs to go through three layers to transfer to the hardware, because the different standards and interfaces of each layer cause the data to be converted back and forth, which starts and runs very slowly. And Hyper-V is placed on top of the physical hardware, only 300k, but the function is very powerful, it is to connect the hardware and the virtual machine, its location is lower than the system kernel, from it up can be regarded as a virtual machine, including Windows server 2008. Considering the shortness of Hyper-V and the improvement of VMBus speed, it is much more advanced than the original virtualization products to contact virtual machines and hardware under Emulation (simulation layer), so it is very easy to run virtual machines in Windows server 2008.

II. CPU and kernel requirements

Today's CPU products, whether AMD or Intle, indicate support for virtualization products as long as they are marked with AMD-V or Intel VT. In the operating system, the Hyper-V requirement is 64-bit, and the 32-bit is abandoned because running more than a dozen virtual machines on a server that only supports 4G memory shows that it is running out of steam and doesn't make much sense.

Summary: hardware requirements for running Hyper-V:

1. Server 2008 Enterprise or Datacenter version

2. 64-bit processor supports virtualization

3. Memory at least 4 gigabytes

4. Multiple hard disk partitions

5. At least 2 network cards, one for virtual machine sharing and one for real physical machine use

Third, the application of Hyper-V

1. Create a new partition to store the virtual machine, and form a VHD device after volume naming, system file definition, and formatting. As shown in figure 1.

2, add the role of Hyper-V in the server manager, in the add role wizard, check the "Hyper-V" item to make sure that the network card used by the virtual machine is used for future communication. As shown in figure 2. After a short period of processing, Hyper-V was successfully installed.

3. Next, you can create a virtual machine. HYPERV appears in "Server Manager-> role-> Hyper-V- > Hyper-V Manager". There are no virtual machines yet. Create a virtual machine through the new one in the right column, as shown in figure 3.

4. Execute the virtual machine creation wizard, define the server type for it (for example, as a WDS server), and specify the previously created target partition, as shown in figure 4. Click next to allocate memory to it. The default is 512m, and the recommended range is 8M-4G. Click next to determine whether to use the virtual network card and the associated virtual partition, that is, the target partition we created earlier.

5, determine which way to install the operating system on the virtual machine: later, through the CD/DVD-ROM or iso image file, boot floppy disk, network installation server, etc. As shown in figure 5, after determining the installation of Windows server 2008 with the CD, the remaining thing is how to configure the WDS server. At this point, a virtual machine is installed successfully.
