I'm following . I have a compute node, a neutron network node and a controller. I noticed that when I've sourced I can't see the dotted quad for the external network: <-- (If you click the arrows in the top-right corner the formatting gets fixed.)

I set up the external network thus:

neutron subnet-create ext-net --name ext-subnet --allocation-pool start=,end= --disable-dhcp --disable-dhcp --gateway

And the tenant net like so:

neutron subnet-create demo-net0 --name demo-subnet0 --gateway

So far the only error I see is in nova-api.log.

Hi, I had the same issue.You need to add,

vif_plugging_is_fatal = False vif_plugging_timeout = 0

in /etc/nova/nova.conf This should resolve it.

Thanks. I tried adding those two lines to the DEFAULT section of my nova.conf file on the controller machine. The build is stuck in Task State 'spawning'.

Also tried them in the [neutron] section. Did not work. Here is my nova.conf

I ran 'ovs-vsctl add-port br-ex' then 'ovs-vsctl add-port br-ex eth0' where eth0 is my net node's management interface. Then I restarted all my neutron services and there was no eth0-br.

My network node's ifconfig.
