[Openstack] Grizzly GRE tunneling network set up problems
I just set up a multi-node Grizzly release 2013.2 with 1 controller
node, 1 network node and 1 compute node. I use GRE tunneling.
I create one VM on the compute node and was not able to ssh to it using netns.
One thing I noticed is that on my compute node, I do not have br-int
and br-tun in the list, nor do I find any GRE tunnels. Am I supposed
to create the GRE tunnels manually or they should be set up
automatically by Quantum? Any idea or suggestion to make it work?
Thanks in advance!

Re: [Openstack] Grizzly GRE tunneling network set up problems
Hi Haitao,
There should be GRE full mesh links being created in br-tun while you
created a VM successfully in Quantum ovs plugin GRE mode, just like:
Bridge br-tun
Port "gre-x"
Interface "gre-x"
type: gre
options: {in_key=flow, out_key=flow,
remote_ip="xx.xx.xx.xx"}
Maybe you can check if there any error in log file
(/var/log/quantum/openvswitch-agent.log in compute node and network node),
perhaps you have wrong setting in quantum.conf (rabbit_host or others)

Re: [Openstack] Grizzly GRE tunneling network set up problems
I'd check the quantum openvswitch agent log files. I'd guess the reason
this isn't working is because your kernel isn't using the openvswitch
kernel module that has tunnel support.

Re: [Openstack] Grizzly GRE tunneling network set up problems
Aaron & Chandler
Thanks a lot for the help. I should have mentioned that the host OS is
CentOS 6.4 (specifically the kernel from RedHat RDO). I googled and
found that it may not have gre tunneling support. Is there anyone who
has successfully set up gre with RDO's kernel or it is just can not be
done and I should use the VLAN.
As Aaron suspected, there are errprs in the OVS agent log:
system@ovs-system: failed to add gre-3 as port: Address family not
supported by protocol
More details below
Any pointer will be highly appreciated!

Re: [Openstack] Grizzly GRE tunneling network set up problems
You should be able to compile openvswitch from source here :
http://openvswitch.org/download/ and then you'll get tunnel support.

Re: [Openstack] Grizzly GRE tunneling network set up problems
You should follow the instructions here:
http://git.openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob;f=INSTALL;h=5589fe7dd7203308bbec27a562cb9899d218577a;hb=a4fff9cc390b69bde1257b414212505a72c4b450
