the OpenStack API traffic, and management traffic.
.. warning::
When using a single interface networking setup, there will be a
temporary network outage as your IP address is moved from the
physical NIC of your machine, to the OVS bridge. If you are SSH'd
into the machine from another computer, there is a risk of being
disconnected from your ssh session (due to arp cache
invalidation), which would stop the stack.sh or leave it in an
unfinished state. In these cases, start stack.sh inside its own
screen session so it can continue to run.
