Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I was able to clone a Ubuntu 10.04 server residing in Cloud. It appeared that I was not getting some IP for the new VM so I followed some of these:

# cd /etc/udev/rules.d
# cp 70-persistent-net.rules /root/
# rm 70-persistent-net.rules
# reboot

I didn't follow the later commands as I was unable to see two eth MACs as available in the referenced site.
After this I am able to see some the IP for it, and is different form the original IP, I have added new IP to DNS server.

Now when I try to access it with its assigned(new) domain it is directed to the old server. I can see both the VMs running with different IP.

Where I might have gone wrong, I am new to this admin thing.

EDIT: Both the system had different eth0 hardware address for ifconfig. I had set up password less login for only one (old) IP (server), trying to login to to new IP, it logged me in without password. Am I now logging on the same server (IP got confused)?

does it work when you connect to the new ip-address? yes: check your new and old dns entries –  user582846 Oct 17 '12 at 9:27
    
yes, I can login using ssh to both the old and new IPs. –  tough Oct 17 '12 at 9:42
    
I have as well checked both the DNS entries and they are right as I had used the same domain for another server/clone and was working for me, now I have just changed the IP in the DNS entries as I am not using the old clone for now. Hope this helps to answer this, please let me know if some more information is needed (I am not sure what else matters in this case) –  tough Oct 17 '12 at 10:31
