<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">First
a disclaimer: I’m working on Ubuntu and Icehouse, so
you might have different behavior, based on your
distributions. Also, I don’t have all the specifics
and flags you might need, but hopefully this can
point you in the right direction. Also, also, the
design below accounts for some VLAN segregation, and
may be more complicated than what you need.</span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Since
you already have the eth devices created, and
assuming your routing is correct: I would create a
new bridge for each vlan with ovs-vsctl (say,
br-ex803 and br-ex805). If you look at <a href="http://openvswitch.org/support/dist-docs/ovs-vsctl.8.txt" target="_blank">
http://openvswitch.org/support/dist-docs/ovs-vsctl.8.txt</a> you can
find the syntax for add-br to create the bridge,
then add-port to bind it to the eth device. You can
also use ovs-vsctl to set the trunks property on the
port, after it’s created, which you’ll need for the
vlan tagging. Then, create a new physnet to match
each one of those (physnet3, physnet4, etc) and
include them in the bridge-mapping as
“physnet3:br-ex803”, or something similar, and
specify the VLANs as belonging to that particular
physnet in the network_vlan_ranges parameter, like
“…physnet3:803,physnet4:805”. </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">After
all that, you’ll need to update the neutron sql
database so the entry in the network segments table
will point to the correct physnet. Search it by the
UUID of the network you’re creating, and update the
physical_network property to match “physnet3” or
whatever you create. Then you can create a subnet
from that network, allocate from it, and it should
work. You’ll also need to restart the
openvswitch-agent and the L3-agent, probably before
you create the subnet.</span></p>
