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.
