access VM from inside itself by its float IP, flatDHCP mode

Can somebody approve that this is the case of what is said in docs - "Note that you cannot SSH to an instance with a public IP from within the same server as the routing configuration won't allow it." (here http://docs.openstack.org/trunk/openstack-compute/admin/content/associating-public-ip.html )

And the only decision is to do it manually via smth like iptables/route in the VM itself? i.e route VM_realIP to VM_privateIP inside VM

The probles was caused, that for example you have an http file/object server which make URL to objects like http://IP/object binded together with some web-service on that objects that need to access them via http locally and remotelly.

my real case:
We have working implementation of some package on real node, but to make it work in the cloud we had to make object like innerIP and outerIP -i.e. some kind of change concept and code rewriting.
To me it looks like this is not very rare case, especially if you not know exactly what must be public and what is localhost_like enough.

As a part of solution, I was adviced to use hostname(as of EC2 practice) which dnsmasq on nova-network give to an instance. In global world that must be done with real DNS, I think. So the case of use publicIP from within VM itself is rare. But if one cannot make DNS record for publicIP and want to access objects both from inside VM and from other service outside it(and mb outside the cloud at all) there still must be concept of inner and public IPs for objects URLs naming.

This should work now that the fix for bug 933640 is in

Ok. Thank you, Vish!
Need to add that to docs.
