VirtualBox Ubuntu virtual machine does not solve the problem of Internet

1. If the physical machine is through wired internet, then need to use the NAT network connection, if it is a wireless network, then need to use bridging way to the Internet

For bridging, the gateway for the virtual machine needs to be set to the gateway of the physical machine:

1) vi/etc/network/interfaces

2) Restart the network/etc/init.d/networking restart

If still not, such as Ping www.baidu.com, the report: Ping:unknown host www.baidu.com at this time can use the GOOGL public DNS

Cat/etc/resolv.conf
