Hi Brian,
Maybe there's a really simple solution but I don't have enough info to
tell. So here's a "slightly" longer suggestion.
For VLAN support on the *physical* network your switch will need to
support 802.1Q. When you say VLANs what do you mean? If you want to use
VLANs for tenant separation (so in the overlay network, not the physical
network) then Open vSwitch will take of that and AFAIK (I don't use
VLANs) you don't need to enable VLANs on your ifcfg devices. Unless your
physical network requires VLANs off course.
The interfaces you pasted had VLAN=yes but not a VLAN designation (like
DEVICE=eth0.10 where .10 indicates VLAN 10) and although configured for
a static setting (DHCP commented out) there was no IP address defined.
So maybe take a step back. Delete all the networks and routers (might
need to do that from the CLI if things are stuck), on your Neutron node
backup & delete ifcfg-br-ex and restore a working ifcfg-eth0, then
restart the network and restart the Open vSwitch service on your neutron
node so it detects previous stuff is gone (check with ovs-vsctl show),
then start with defining the ifcfg-br-ex device and make sure your
network is OK first (check with ip address show and restart the network
and check again). Then add ethX to br-ex:
# ovs-vsctl add-port br-ex ethX ; service network restart
Make sure you have access to a local console so you don't get locked out
if your network fails to restart. Then restart the Open vSwitch service.
Then move on to create the tenant stuff you'll need. I don't know how
you installed RDO. If you used Packstack and want VLAN tenant separation
then you have already provided VLAN info and you should use that when
setting things up with something like:
As regular user:
the router
the private network
the private subnet
add private subnet to router
As admin:
the public network (to be used for example to access the Internet)
the public subnet
add public gateway on the router
As regular user:
Create some floating IPs
Start an instance of for example the Cirros image
Assign a floating IP address
Once booted log into it via the console, ping local & remote addresses.
Hopefully shout "YES!" :)
FWIW: If you want VLANs for tenant separation then VXLAN and GRE are
much easier: Read Rhyz's explanation (5th comment) why:
