+Open vSwitch is a production quality, multilayer virtual switch licensed
+under the open source Apache 2.0 license. It is designed to enable
+massive network automation through programmatic extension, while still
+supporting standard management interfaces (e.g. NetFlow, sFlow, RSPAN,
+ERSPAN, CLI). In addition, it is designed to support distribution
+across multiple physical servers similar to VMware.s vNetwork distributed
+vswitch or Cisco.s Nexus 1000V.
+
+Open vSwitch can operate both as a soft switch running within the
+hypervisor, and as the control stack for switching silicon. It has been
+ported to multiple virtualization platforms and switching chipsets. It
+is the default switch in the Xen Cloud Platform and also supports Xen,
+XenServer, KVM, and VirtualBox. The bulk of the code is written in
+platform-independent C and is easily ported to other environments.
+
+This package will build kernel modules that will be uses as replacements
+for the bridge modules included with the stock Linux kernel. Open
+vSwitch includes a kernel module if you wish to use the standard Linux
+bridge utils to manage it.

+Here are some scripts that I've written for use with Xen at my site.
+In order to use these scripts with your Xen installation you'll need to copy
+both the network-openvswitch and vif-openvswitch files to your
+/etc/xen/scripts directory. You can instruct Xen to use these scripts by
+editing your /etc/xen/xend-config.sxp file and specifying these scripts as
+the default network-script and vif-script.
+
+For example, here are the entries in my xend-config.sxp file:
+
+ (network-script 'network-openvswitch netdev=eth2 bridge=ovs0')
+
+ (vif-script 'vif-openvswitch bridge=ovs0')
+
+If your network interface card and attached network switch support VLAN
+tagged traffic, you can place virtual machines within a seperate VLAN by
+appending a '.' and the VLAN tag number you wish the domain to use. For
+example, to have all domains default to VLAN 2 you can do the following:
+
+ (vif-script 'vif-openvswitch bridge=ovs0.2')
+
+You can also specify tagged traffic in the domain configuration file.
+
+If you are hosting a hardware virtualized domain understand that the
+/etc/xen/scripts/qemu-ifup script is run instead of the vif-script specified
+in the xend-config.sxp file. You'll need to edit this file to add the port
+to the vswitch instead of using the brctl (unless of course you are using
+the appropriate kernel module to control the vswitch using brctl.) Here is
+a snippet from my qemu-ifup to handle hardware virtualized ports:
+
+ if lsmod | grep -c openvswitch_mod 1> /dev/null && ! lsmod | grep -c brcompat_mod 1> /dev/null
+ then
+ ovs-vsctl -- --may-exist add-port $bridge $1
+ else
+ brctl addif $bridge $1 || true
+ fi
+
+This doesn't handle tagged traffic. I'll leave that as an exercise for you.
+
+Enjoy.
