HI,

If your set up is multi-host dhcp, the VM's gateway should be the the IP address of the compute node.

From the controller check the result of

nova-manage network list

From inside the VM, check the result of

route -n

Also, I am wondering why you have assigned a public IP in your VM. It could also be setup in such a way that your instance will just get a fixed IP and assign a floating IP.

If your set up is multi-host dhcp, the compute node will act as the gateway of the VM. Make sure first that the compute node can access the internet. Additionally, the VM's gateway should be the the IP address of the compute node.

node. From inside the VM, VM you can check the result of

this by route -n-n.

Another thing that might be usable is to add add routing_source_ip in nova.conf
