I did have a problem in vlan trunking on the switch. I fixed it. Now, I am able to ping and ssh the instance that is launched on the compute node from the controller. However, when I look into euca-get-console-output of that instance on compute node, I still see that it is not able to connect to 169.254.169.254 (metadata service). But, I see a private ip address getting leased correctly. Because of this I am able to ping and ssh successfully from CONTROLLER ONLY (not from compute node). I am not sure if this is the correct behavior. But, in case of flatDHCP this metadata connection should be successful. Otherwise, instances cannot be pinged/sshed in flatDHCP mode. Can VLAN be run in multi-host mode like it is done in flatDHCP mode as suggested by Sergio Ariel below?

However, I still cannot ping this ip address from the network(controller node). I am running nova-network service only on the controller." "can't connect to remote host (169.254.169.254): Network is unreachable" I "solved" it when I installed nova-network in all my compute nodes. I don´t use NAT but only routing, so each node is the default gateway to instances that are running on it. I don´t know if this workaround is good for you, but it is the best I got. Regards....

I would suspect that you actually don't have the vlans trunked on the ports so the packets aren't making it across the switch. Vish On May 31, 2012, at 9:53 AM, Vijay wrote: Thanks for the reply.
