Thanks for your response.
BTW, is it possible to make the quantum + OpenVSwitch + VLAN type workable
on my RHEL6.3? I am trying this in my environment, but my VM can not get IP
address without any error in the quantum or compute log files.

That's right, the Open vSwitch FAQ says:
Q: What features are not available in the Open vSwitch kernel datapath
that ships as part of the upstream Linux kernel?
A: The kernel module in upstream Linux 3.3 and later does not include
the following features:
- Bridge compatibility, that is, support for the ovs-brcompatd
daemon that (if you enable it) lets "brctl" and other Linux
bridge tools transparently work with Open vSwitch instead.
We do not expect bridge compatibility to ever be available in
upstream Linux. If you need bridge compatibility, use the
kernel module from the Open vSwitch distribution instead of the
upstream Linux kernel module.
- Tunnel virtual ports, that is, interfaces with type "gre",
"ipsec_gre", "capwap". It is possible to create tunnels in
Linux and attach them to Open vSwitch as system devices.
However, they cannot be dynamically created through the OVSDB
protocol or set the tunnel ids as a flow action.
Work is in progress in adding these features to the upstream
Linux version of the Open vSwitch kernel module. For now, if
you need these features, use the kernel module from the Open
vSwitch distribution instead of the upstream Linux kernel
module.
- Patch virtual ports, that is, interfaces with type "patch".
You can use Linux "veth" devices as a substitute.
We don't have any plans to add patch ports upstream.

Hi ShaKe,
Do you mean the latest OpenVSwitch for RHEL 6.3 does not support GRE
module or something else?

Can anyone help to confirm that the GRE Tunneling can be used with
Quantum on my RHEL6.3?
My Redhat kernel version is 2.6.32-279.el6.x86_64, and the
OpenVSwitch version is 1.4.2. From the wiki page(
http://wiki.openstack.org/ConfigureOpenvswitch) , I find some
modules are still not available in RHEL.
If I want to use the GRE Tunneling, need I upgrade my linux kernel
or OpenVSwitch?
Thanks!
