Hi Sriharsha, Can you check the following on your router?
1. When you start the VM. Do you see the VM's MAC, IP info being recorded in /etc/dhcphosts.txt file on your router VM? 2. Also please make sure that /etc/dnsmasq.conf on your router contains the following lines Dhcp-range=<IP From your guest subnet/router's guest IP>,static Few other checks might help you here: On your Guest VM, (I) Are you sure that eth0 is what your current interface active? Please check "ifconfig -a or dmesg" to see what eth interfaces are created by system. (II) If it is something else other than eth0, can you try "dhclient ethX" and see whether that works or not?
