I follow https://simplenfv.wordpress.com/2016/05/16/deploying-openstack-on-just-one-hosted-server/

on 32 GB box . Everything goes fine. Finally I get :-

I would expect br-ex on Controller belong   192.168.23.0/24


Due to on VIRTHOST :-


[root at ServerCentOS72 ~]# virsh net-dumpxml external
<network>
  <name>external</name>
  <uuid>d585615b-c1c5-4e30-bf2d-ea247591c2b0</uuid>
  <forward mode='nat'>
    <nat>
      <port start='1024' end='65535'/>
    </nat>
  </forward>
  <bridge name='brext' stp='off' delay='0'/>
  <mac address='52:54:00:9d:b4:1d'/>
  <ip address='192.168.23.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.23.10' end='192.168.23.50'/>
    </dhcp>
  </ip>
</network>


I am missing something here external network is the same as VTEPs network between Controller && Compute.

Please, advise.   I just followed instructions . Zero manual intervention from my side.


Thanks.

Boris.
