[Openstack-operators] Help - Trying to install OpenStack - Network issues

I think I've found the cause of the problem.

I've made a mix of combinations in my /etc/network/interfaces file and
after I uncommented the following lines, it stopped working.

# OpenStack Networking VXLAN (tunnel/overlay) bridge
#
# Only the COMPUTE and NETWORK nodes must have an IP address
# on this bridge. When used by infrastructure nodes, the
# IP addresses are assigned to containers which use this
# bridge.
#
auto br-vxlan
iface br-vxlan inet manual
    bridge_stp off
    bridge_waitport 0
    bridge_fd 0
    bridge_ports bond0.30

Still trying to figure out why this doesn't work and the other (and
similar) config does.

BR,

R
