centos 6.2

Unless you selected the network service to start by default, then it's probably not up.

Try:
ifup eth0

Then, if it comes up, make sure to enable it for ONBOOT.

vi /etc/sysconfig/network-scripts/ifcfg-eth0

Add/edit the file to make it say
ONBOOT="yes"

And that should be it.

Hi

Where is screen shot dear???which screen shot i have to folow to configure in correctly???

screen shot here was mentioned in context of what you had provided.

The error which it was providing was due to network connectivity
/etc/yum.repos.d/(filename).repo
baseurl = ""
domain name mirrorlist.centos.org was not able to resolve

now in this case you do following thing to resolve the issue
Connect your virtual centos machine to internet
or
configure yum repository using install cd.

If you host machine has connectivity then add loopback adapter on base machine so that your virtual ubantu can connect.

Configuration of network can be done by using

setup

Network

command where you can assign static or manual IP also check vmware network setting.
