This is going to cause some ambiguity in the networking. Another possible issue could be a loop created by OVS, brmgmt and brbond705 (this may depend on other config).</div><div class=""><br class=""></div><div class="">I'm guessing ext_net is for Neutron external networking, in which case you can drop the ext_net VLAN definition in Kayobe config - you'll need to define it in Neutron instead. For Kayobe, listing ext_net in external_net_names should be enough to ensure it gets an OVS bridge attached to it.</div><div class=""><br class=""></div><div class="">With the two networks you have defined (mgmt_net and ext_net), the minimal setup would be:</div><div class=""><br class=""></div><div class="">- remove the VLAN definition for ext_net_vlan</div><div class="">- define ext_net as bond0.</div><div class="">- mgmt_net as a VLAN device tapped off bond0, eg "{{ ext_net_interface }}.{{ mgmt_net_vlan }}"</div><div class=""><br class=""></div><div class="">With ext_net listed in external_net_names, this will set Kayobe to attach bond0 as the external OVS port.</div><div class=""><br class=""></div><div class="">Note, we normally configure more logical networks than this.
