Open Stack

Are you running multi_host, as in nova-network on both nodes? I would check ip_forward is enabled on both nodes. Nova-network creates an snat rule so that Instances can get to the outside world, so you should also make sure that the snat rule exists and seems to be working properly.

The odd thing is, it *does* successfully do a dns lookup. Additionally, it can ping other instances on the private network address range.
