Host machine, virtual machine linux, development board linux network settings (can ping each other)

got a long time (about 3 days), and finally got through. At first I wanted to give up but slowly began to know the problem. Still the same sentence: Persistence is victory! !

First look at the host's ip, as shown in the figure

Then look at the virtual machine linux ip, as shown:
Finally look at the development board ip, as shown in Figure

It is also important to set up a virtual machine! ! ! ! ! !

Select the virtual machine as shown in the figure---Settings:

Pop-up box as shown in the figure: Set the network to be configured, select the bridge
Select the editing of the virtual machine-----Edit the virtual network
