Network is unreachable in Ubuntu 14.04 on Virtualbox using bridged adaptor staic ip

I got Network is unreachable in Ubuntu 14.04 on Virtualbox using bridged adaptor as a VM server.

In /etc/network/interfaces:

auto lo
iface lo inet loopback


source /etc/network/interfaces.d/*.cfg


auto eth0
iface eth0 inet static
address 192.168.1.198
netmask 255.255.255.0

to ifconfig command:


eth0 Link encap:Ethernet HWaddr 08:00:27:f2:f2:d9

If I ran ping to other internal device such as 192.168.1.* then it is working. If I ran ping 8.8.8.8, it showed Network is unreachable. Is there any setting I am missing?
Thanks a lot
