network/openvswitch: Removed (build failure)

The code in upstream's git repo might build, but it's not
even in a beta status yet, so it will have to wait (but of
course the SBo maintainer is free to begin testing already)

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.

# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description. Line
# up the first '|' above the ':' following the base package name, and the '|' on
# the right side marks the last column you can put a character in. You must make
# exactly 11 lines for the formatting to be correct. It's also customary to
# leave one space after the ':'.

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.

# This script creates a virtual switch (default ${netdev}) and adds a
