<font size="2" face="sans-serif">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.</font><br>

<p><font size="3" face="serif">That's right, the Open vSwitch FAQ says:</font>
<p><font size="3" face="serif">Q: What features are not available in the Open vSwitch kernel datapath<br>
that ships as part of the upstream Linux kernel?</font>
<p><font size="3" face="serif">A: The kernel module in upstream Linux 3.3 and later does not include<br>
the following features:</font>
<p><font size="3" face="serif"> - Bridge compatibility, that is, support for the ovs-brcompatd<br>
daemon that (if you enable it) lets "brctl" and other Linux<br>
bridge tools transparently work with Open vSwitch instead.</font>
<p><font size="3" face="serif"> We do not expect bridge compatibility to ever be available in<br>
upstream Linux. If you need bridge compatibility, use the<br>
kernel module from the Open vSwitch distribution instead of the<br>
upstream Linux kernel module.</font>
<p><font size="3" face="serif"> - Tunnel virtual ports, that is, interfaces with type "gre",<br>
"ipsec_gre", "capwap". It is possible to create tunnels in<br>
Linux and attach them to Open vSwitch as system devices.<br>
However, they cannot be dynamically created through the OVSDB<br>
protocol or set the tunnel ids as a flow action.</font>
<p><font size="3" face="serif"> Work is in progress in adding these features to the upstream<br>
Linux version of the Open vSwitch kernel module. For now, if<br>
you need these features, use the kernel module from the Open<br>
vSwitch distribution instead of the upstream Linux kernel<br>
module.</font>
<p><font size="3" face="serif"> - Patch virtual ports, that is, interfaces with type "patch".<br>
You can use Linux "veth" devices as a substitute.</font>
<p><font size="3" face="serif"> We don't have any plans to add patch ports upstream.</font>

My Redhat kernel version is 2.6.32-279.el6.x86_64, and the OpenVSwitch version is 1.4.2. From the wiki page(</font><a href="http://wiki.openstack.org/ConfigureOpenvswitch" target="_blank"><font size="3" color="#0000FF" face="serif"><u>http://wiki.openstack.org/ConfigureOpenvswitch</u></font></a><font size="3" face="serif">)</font><font size="3" face="sans-serif"> , I find some modules are still not available in RHEL.<br>

If I want to use the GRE Tunneling, need I upgrade my linux kernel or OpenVSwitch?<br>

Thanks!<br>
