![]() ![]() Private Virtual Networks are great if you need total isolation from all other Virtual Networks, but they can sometimes be problematic if you need to copy files to the virtual machines, since there is no connectivity to any physical network or to the Host operating system. Guest operating systems that are connected to the same Private Virtual Network can communicate with each other, but they cannot communicate with the Host operating system and the Host operating system cannot connect to the VMs on the Private Virtual Network. There are three types of virtual networks that you can connect to in Hyper-V:Ī Private Virtual Network is a virtual switch to which only virtual machines can connect. It’s a good idea to create different virtual switches if you have scenarios where you need to have network isolation similar to what you would have on a physical network, where the different segments are separated by firewalls or some other access control device. ![]() If you want hosts that are connected to one virtual switch to communicate with hosts that are on another virtual switch, you can create a virtual router, VPN server, firewall or similar device to those you would have on a physical network. Each virtual switch is logically isolated from all other virtual switches. All the virtual machines that connect to the same virtual network switch are connected to the same switch. Consider a virtual network to be like a switch, but instead of a physical switch, it’s a virtual switch. The concept of a virtual network is an important one to understand. For example, external virtual networks are basically on physical NICs, so you can only have the number of external networks that is the same as the number of physical NICs. ![]() There is no limit on the number of virtual switches you can create – depending on the type of virtual network you are working with. The Virtual Network Manager is responsible for creating and controlling virtual switches. With Hyper-V, the guest operating systems never have direct access to the hardware, and the Hyper-V management interfaces control the traffic moving through the physical and virtual interfaces. Networking in Hyper-V is sort of interesting for those who are used to physical networking or are used to the way networking is implemented in VMware. ![]()
