(reprinted) Configuring the Network method when Hyper-V is used in the WINDOWS8 system

With the virtual machine role enabled, your physical device needs to be shared with all virtual machines (your Windows 8 also becomes a virtual machine, because it also goes through the virtualization layer when it uses physical devices, and of course, if Hyper-V is turned on, your hardware supports virtualization, in other words, the performance penalty is low, so There is no need to worry about Windows 8 performance damage to turn on virtualization. ）

Because CPU, memory allocation is adjusted in the settings of the virtual machine, so, before you start using Hyper-V, you need to consider the virtual switch, that is, the physical network card into a virtual switch, and then virtual a network card to the physical machine (just said, your windows 8 is already a virtual machine, of course, the use of virtual network card is not surprising. It sounds complicated. How to become a virtual switch and configure a virtual network card for Windows 8.   　　In fact, is to let everyone understand the principle, in writing so much.   　　The actual operation is very simple oh. Select Virtual Switch Manager on the virtual machine console

In the new virtual network switch, select External, and then tap create Virtual Switch

Give a "name", the following select "External network" (otherwise can not connect to other machines and the Internet OH), the following list to select the physical device, such as the choice of a wired network card or wireless card, can be. Here I choose the wired network card to do the virtual switch.

Then select OK

You are prompted to modify the NIC configuration, so the network temporarily interrupts for a while, you click "Yes" to start the configuration. A few seconds will be almost ready.

You can verify that your physical network card will become a virtual switch, all of the configuration disappears, only the original one protocol, "Hyper-V Extensible Virtual Switch" protocol Oh, of course, you can not move oh, nothing to give it an IP, you will find the host and virtual machine network is not normal,   　　So don't touch it's configuration oh. The configuration of the physical network card will be copied to a new virtual network card, so, there is no need to worry, if you need to modify the dynamic IP, static IP, and so on, to modify the "vEthernet (the parentheses are you from the virtual net name)", OK.
