Host and virtual machine file transfer moves: https://blog.csdn.net/qq_38786209/article/details/79984879
notice:! ! !
There may be many reasons why the virtual machine cannot access the Internet, but if there are no special requirements and you just want to connect to the Internet as soon as possible, the following methods are recommended.
The virtual machine cannot access the Internet:
Scenario 1 : If the virtual machine is just installed, the host is connected to a wireless network (WIFI), but the virtual machine cannot access the Internet, remember to directly change the network mode to bridge mode and uncheck the copy network connection, so that Getting online right away is one of the easiest ways to get online.
As shown in the figure: Right-click on the virtual machine option, select the settings button,
then change the network mode to bridge mode and uncheck the duplicate network connection,
and then you can connect to the network immediately.
Situation 2 : This time I suddenly did nothing and couldn't connect to the Internet, and then I tried to find that it could be solved like this.
Workstation->Edit->Virtual Machine Network Editor->Change Settings As shown in the
figure :
Select Bridge Mode -> Automatically select the wireless network card of the external computer (it cannot automatically find a network card that can connect to the Internet), as shown in the figure:
If you don't know which is your own network card, you can view the network properties under Windows settings and find your own network card as shown in the figure:
Situation 3 : Still unable to connect to the Internet, the solution: open the network connection, right-click properties of the local connection "Microsoft Wi-Fi Direct Virtual Adapter #3", double-click IPv4, and change to obtain IP automatically, as shown in the figure:
Painful attempt (you can skip ): This problem bothered me for an afternoon and an evening, looking for blogs in various ways. I also heard from the teaching assistant that virtual machines are more likely to encounter various network problems, and suggested that I install dual systems. But I have tried several times, the computer does not know why, it can only boot the dual system from the U disk; if it is partitioned separately, it will freeze when restarting after the installation is successful, and then every time the boot is turned on, the screen will be black, and the dual system cannot be entered normally. It didn't work out all night. ——-Remember a painful lesson that the Ubuntu virtual machine cannot connect to the Internet.
