This process is not duplicated when you work with Hyper-V on Server Core. Because you use a command line to add the Hyper-V role you do not get to create a virtual network switch. Instead the virtual network switch must be created manually after the role installation and its corresponding reboot. External connections will automatically be linked to the virtual network switch. In this case all network traffic is routed through the virtual switch as if it were a physical switch see Figure 2-27 . Because the external connection is linked to a port on the virtual switch applications within the VM that must connect externally will have all traffic routed through the virtual network adapter to the port on the virtual switch then through the physical network adapter and out to the external world. 108 CHAPTER 2 Configuring Hyper-V Hosts VMOne Networking NIC Application Virtual Switch VMTwo Virtual NIC binding All except Microsoft virtual network switch protocol Physical NIC binding Microsoft virtual network switch protocol Physical Physical Server FIGURE 2-27 The operation of an external network in Hyper-V Internal connections are not linked to the virtual network switch. Because of this they can only communicate with the host and with other virtual machines bound to the same network see Figure 2-28 . Private networks are not linked to the virtual network switch either. They only provide access to other virtual machines linked to the same network see Figure 2-29 . Hyper-V can emulate two different types of network adapters the network adapter and the legacy network adapter. For virtual machines to be able to work with the network adapter they must be able to install and run the Hyper-V Integration .
