1 : First, we confirm the version of ubuntu###

cat /etc/issue or
sudo lsb_release -a or
uname -a

I am here ubuntu16.04

2 : Set the virtual machine's network connection mode to bridge

3 : Ipconfig to view the ip information of Host###

4 : Ifconfig view system network card information###

5 : Manually set static ip

vim /etc/network/interfaces

**# Add the following **
