Re: [openstack-dev] setting up 1-node devstack + ml2 + vxlan
To more precise, the kernel will listen on udp port 8472 as soon as you create a vxlan port, with ip_route2. I doubt it's your case, but i can't figure out why you want to change the vxlan port? please tell us about that, it could be interesting. In your case, your config doesn't seem to be a multi-node one, so you will have only one vxlan endpoint, which hosts network node and compute node. If this is right, it's normal that no vxlan tunnel is created, since you don't have any other vxlan endpoint.

Re: [openstack-dev] setting up 1-node devstack + ml2 + vxlan
Please look at my last reply. Do you have several compute nodes? If you have only one node, you won't have any vxlan port on br-tun.

[openstack-dev] setting up 1-node devstack + ml2 + vxlan
Folks,
I'm trying to set up a simple single-node devstack + ml2 + vxlan
combination, and though this ought to be a simple RTFM exercise,
I'm having some trouble setting this up. Perhaps I'm doing something
wrong- clues would be welcome.
I made sure to use ovs_version 1.10.2, and followed
the instructions in https://wiki.openstack.org/wiki/Neutron/ML2
(and then some, based on various and sundry blogs that google found)
Can someone share (all) the contents of their localrc,
and if possible, a description of their VM (virtualbox? qemu-kvm?)
setup so that I can compare against my env?
FWIW, I tried the attached configs.
localrc.all - sets up
Q_PLUGIN=ml2
Q_ML2_TENANT_NETWORK_TYPE=vxlan
Q_AGENT_EXTRA_AGENT_OPTS=(tunnel_type=vxlan vxlan_udp_port=8472)
Q_SRV_EXTRA_OPTS=(tenant_network_type=vxlan)
Resulting VM boots, but no vxlan interfaces show up (see ovs-ctl.out.all)
localrc.vxlan.only - disallow anything other than vxlan and gre.
VM does not boot- I get a binding_failed error. See ovs-ctl.out.vxlan.only
Thanks in advance,
Sowmini
