[openstack-dev] [Baremetal][Neutron] SDN Solution for Openstack Baremetal Driver

Hi fellow stacker,

I am designing for a Baremetal stack with SDN support recently and would
like to seek for the help from you all for how to do so.

I am building an automated testing framework on top of Openstack Havana.
For performance and platform sake I would need to provision my stack using
baremetal driver (Not Ironic). But on the other hand I also need the
network virtualization provided by neutron in order to maximize resource
utilization. Therefore I started looking for SDN solutions for the
baremetal use case. My network infrastructure is from Cisco and so I
started with Cisco plugin within Neutron.

According to [1], I found that the plugin pretty much supported all
functionality for the virtualized VM case (i.e. dynamical VLAN creation and
VLAN tag propagation from controller to compute host). But for baremetal
case, it seems that the solution would not work as there is no OVS agent
running on the BM node.

Since information about baremetal + SDN is quit lacking so I wonder if
anybody here has tried baremetal + SDN before and could share with me your
experience in doing so? Or it is simply impossible to do SDN with baremetal
driver? And how about the case for Ironic? Thanks.

Regards,
Tim
