Hi Atreyee,

Your original interface file says:
----------------------------------------------
    auto lo
    iface lo inet loopback
----------------------------------------------

It means, it has settings only for loopback interface.
Looks like your setup has NetworkManager configured and that is why
before configuring Openstack, Network Manager's settings are being
used for assigning IP address and DNS server to interface eth1 (which
is being used for Internet connection).

Settings you added in /etc/network/interfaces for OpenStack
configurations are not valid to connect you to the Outside Internet.
If your setup belongs to your company's / organisation's private
network, then you need to have correct DNS server as well as  IP
address in config file for eth1 so that Internet would be accessible.


Thanks,
Vivek
