Hello,
I am trying install Essex in VLAN mode on multiple compute nodes.
 
I am able to lauch instances on controller (which also runs nova-compute) and ping/ssh those instances.
I am able to launch instances on compute only node. However, I cannot ping the VM launched  on compute only node.
When i did the euca-get-console-output on that instance, I see that it is not getting an IP leased from DHCP .. Because of that it is not able to reach metadata server.
Any help is appreciated.
 
Console output is
udhcpc (v1.17.2) started
Sending discover...
