Scalable virtual switches for Hyper-V

Windows Server 2012 Abstracts The topology of the physical network in the form of network virtualization, making it easier to achieve the goal of isolation and multi-tenant.

In network virtualization, one of the most important technologies is the extensible switch of Hyper-V.

(the example in this article is shown in Hyper-V under Windows 8, and the actual 2012 is the same)

The network is the most troublesome for those who use Hyper-V at first, and Hyper-V does not have the ability to access a virtual machine like VMware Workstation or previous Microsoft's own VPC with a direct two mouse click.

The concept of scalable switches introduced in Hyper-V

Newcomers must feel, not just a net, but also to make so much trouble, like a VM to point two mouse how good simple and quick.

But Hyper-V is more applied to the production environment, with the VM (not specifically referred to as the default refers to workstation) this more biased experimental environment has a natural difference

Tell me the difference between 3 virtual switches

External Virtual Switch

In this mode, the physical network card will not be virtual into a virtual switch, and in the virtual out of a network card to "inherit" your local network card.

Some people find that after creating an external switch, all the configuration information for their physical network card is gone, and only one Hyper-V Scalable Virtual Switch is selected, as shown

Then worry about the local network card even the TCP/IP protocol is not enabled this how to surf the Internet?

In fact, this is your physical network card virtual into a virtual switch, the Hyper-V extensible Virtual Switch that is checked is doing this, and the switch, unless it is used for management, does not need IP or anything else, he is only responsible for forwarding the packet, the network based people should know?

So all the other information is not checked.

At the same time, there is another virtual virtual network card (the general name is "Vethernet ({your network card name} Virtual Switch)" in this format) will inherit your own physical network card settings (such as static Ip,dns settings)
