Hyper-v network settings-external connection problem records hyper-v network settings can be set in three ways, commonly used external connections. When www.2cto.com sets an external connection, hyper-v will generate a network card, copy the information of the original physical network card, and install the original physical network card only with the Microsoft Virtual Machine network switch protocol, all others are canceled. Therefore, when operating the Virtual Machine network, it must be in front of the machine. If it is not in front of the machine, the network will be disconnected and the network will not be connected ...... On the newly generated virtual network card, the information of the original physical machine is copied by default. On the NIC address generated by the virtual machine, configure the local IP address, print, share, and other services. You do not need to modify any information about the NIC of the physical machine. I didn't understand it at first. I 've been playing with the NIC of the physical machine, but I didn't make any adjustments to the NIC generated by the virtual machine. I found this was wrong. If you configure information on the NIC of the physical machine, the connection to the virtual machine on the Internet will be very slow, the ping value is very high, and it is almost unavailable. The correct method is as follows: (1) only the vswitch protocol of the Microsoft Virtual Machine is configured on the NIC of the physical machine, and all others are canceled. (2) configure all information, including IP, printing, and sharing, on the Virtual Network Card generated by hyper-v.
