Subject Re: Issue in Advance Networking Instance not able to get IP from VR two in Node Setup
Date Thu, 16 May 2013 22:16:17 GMT
What OS is the VM (Ubuntu / CentOS/?)
You can login to the virtual router and run tcpdump on eth0 to snoop  for
dhcp requests.
You can also look at /var/log/dnsmasq.log inside the virtual router to
debug dhcp issues.
