[libvirt-users] Redhat VM is not getting IP from DHCP

Hi, Below is the steps which I performed but not getting the IP of the guest. * Created a fresh VM (RHEL-6.4-server-x86_64) * Checked ifconfig output ( Getting IP from DHCP server) * Took xml dump. * Changed UUID in the xml * Changed MAC in the xml * Changed Name * defined a another VM using changed xml. * boot it up and checked the ifconfig status.( Not able to get IP) If same steps I follow in fedora guest then it's working as expected (getting the IP from DHCP). Any Suggestions? -- Praveen Kumar
