Hi all,
Just getting my feet wet with Openstack - I've gone through a number
of test installs and things have gone well with the all-in-one
approach (everything on one host). I'm running neutron/ml2/openvswitch
with a GRE tenant network. The main controller box is running
everything and that all works fine.
The external net is 192.168.88.0/24 with physical hosts on .90 and .91.
I'm now trying to expand my cloud to a second node running
nova-compute, openvswitch and the neutron-plugin-openvswitch-agent.
I've followed the Ubuntu 14.04 install guide to the letter aside from
changing things like my_ip and so on to match.
Connectivity between the boxes is fine, they can ping each other etc.
I can boot a VM on the new compute node, but it cannot get DHCP, nor
can I ping it from any host in its tenant network.
/var/log/openvswitch/ovs-vswitchd.log shows a lot of this:
2014-09-03T10:10:20.144Z|00003|tunnel(miss_handler)|WARN|receive

/var/log/neutron/openvswitch-agent.log shows this:

(No VMs booted at the above time but they show up in br-int as
expected when booted)
On the controller I can see the gre tunnel's other end in ovs-vsctl
show in br-tun, and the patch interface there to br-int looks fine.
I've rebuilt the compute box over a couple of times and I'm utterly
lost at this point - any ideas?

Cheers,
James
