How to set up Hyper-V virtual machine NIC?

For companies that are ready to commit to virtualization, many people have questions like this. What services are used to build most of the virtualization? How to set up the physical network card of Hyper-V? Is the virtual machine NIC set external, internal or private?

In fact, any service in the real state can be put into the virtual machine and the actual situation and the prediction of possible situation problems. It turns out that only one host needs to be maintained, and things are simplistic but not cost effective. Virtualization realizes a virtual host that provides multiple services on a single server. Although it increases the complexity of the environment, the cost can be saved.

For example, the real state DNS host is placed on the physical IP, then in the virtual environment, there must be a real network card IP (external IP); the real enterprise internal web host is on the internal network, the virtual environment It can also be given to the internal IP card location. You don't need to think too complicated. The location of the original connection is the same on the virtual host.

For another example, the virtual host's network card can be inserted more than three (see the motherboard), and then subdivided into external, internal, DMZ, VLAN1, VLAN2 and so on. The external network card can be assigned to the virtual hosts A and B. The network card A can be used for external real IP, the internal network card can be assigned to the virtual hosts A and B, and the second network card B can be used as the internal IP.

As for the placement in the same domain, the independent, or to be a separate host, this is correct.
