hi,

regarding the docs for Ubuntu 14.04 "Provider Network"

http://docs.openstack.org/mitaka/install-guide-ubuntu/environment-networking.html (http://docs.openstack.org/mitaka/inst...)

Is it possible if there's is just one NIC? The same for Management and Provider Network?

Andreas

I found docs for:

  • either put this iface to ovs bridge and set up IP there,

https://developer.rackspace.com/blog/neutron-networking-simple-flat-network/ (https://developer.rackspace.com/blog/...)

When I go ahead this way, how does that effect the official docs for ubuntu mentioned above? I'll expect I've to configure the bridge first and then configure neutron networking on top. What parts from ubuntu docs do I've to change then?

This is possible in any cases.

If VLAN for management and providers are different, you could extract mgmt vlan using vconfig, and use iface itself for providers. If you have single network (no VLANS), which is both provider and mgmt, try

  • either put this iface to ovs bridge and set up IP there,
  • or set up linux bridge on this iface, set up IP on there, and connect ovs br-prv to it using vethpair (like OpenStack Fuel does)
