Dear List,
I am beginner of openstack user.
Welcome to the OpenStack community! :)
I setup openstack with RDO on Centos 7.
I have 6 machines:
they have two interfaces enp2s0f0 (10.51.0.x) and enp2s0f1 (213.135.46.x)
on machine x=1 i setup dashboard/neutron-server/nova/cinder/etc.. on
machines 2-6 i setup:
openstack-cinder-api.service,
openstack-cinder-scheduler.service,
openstack-cinder-volume.service,
openstack-nova-api.service,
openstack-nova-compute.service,
openstack-nova-conductor.service,
openstack-nova-consoleauth.service,
openstack-nova-novncproxy.service,
openstack-nova-scheduler.service
I am presuming you want machines 2-6 as "compute nodes" to put VMs on?
If so, you definitely do not want to put anything *other* than the
following on those machines:
openstack-cinder-volume.service
openstack-nova-compute.service
All the other services belong on a "controller node", where you've put
the neutron server, dashboard, database, MQ, etc.
I run the virtual machine instance which have ip 10.0.3.4 (on machine 5)
I setup router on machine 1
I can ping from the virtual instance ip of router.
I see pings from wirtual machine on machine 1 (where sit router)
err, it looks to me that your machine 1 is a controller, not a compute
node? VMs should go on machines 2-6, unless I'm reading something
incorrectly.
But i have totally no idea how to setup network connectivity with
outside world.

So here is your default gateway, on br-ex...
10.51.0.0/24 dev enp2s0f0 proto kernel scope link src 10.51.0.1

6: br-ex: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UNKNOWN qlen 1000
And here, it's indicating br-ex is in an unknown state. Also, br-int is
in DOWN state, not sure if that is related. My guess would be to bring
up br-ex and see what is failing about the bring-up.
Of course, I'm no networking expert so hopefully one of the Neutron devs
can pop in to help. :)
Best,
