Aaron it helps a lot and thank you for that.
Unfortunately in my setup there is no router for the management
interface since it is much simpler and has two interfaces: one that has
an external IP and connects directly to the internet and a second one
with internal (management) network that cannot be reached from the
outside. In such a case can you recommend a setup or point me at a
documentation?
Thanks a lot again,
George

When the documentation refers to testing external connectivity from
the nodes, it does not mean to test connectivity via the External
Interface, irself. It means that you should be able to reach the
external network (Internet) and the other nodes, from each node, via
the Management Interface. The Management Interface is how you will
log in to the nodes via SSH, as well. The network attached to your
Management Interface should have a route out to the Internet and
provide all the connectivity you need to manage the node, install
software, etc...
Hope that helps!

First of all let me thank you very much for your clear replies!
Yes! That makes sense indeed for the Virtual Machines!
What about the compute node itself? If I am not wrong at that
point of
documentation nova-network hasnt been installed or configured. So
how
is it possible the connectivity tests with the external network
to be
successful as shown at that point?
Furthermore if someone wants to have direct SSH access to the
node from
the external network how is that achieved? In general how does
the
physical node itself access the external network?
All the best,
George
