You can access internet on virtual box by two way one is bridge network or host only. today i show you the host only option. First you need to create a Host only network in virtual box virtual box -> file -> preferences -> network -> Host-only network Click add button Click DHCP, click Enable Server Select virtual OS, go to setting -> network Now login to your ubuntu os and do the following sudoedit /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback # NAT auto eth0 iface eth0 inet dhcp # Host only auto eth1 iface eth1 inet dhcp After VM reboot hope everything worked fine.
