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.

# 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

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.

# Script for configuring a vif using Open vSwitch.

# Usage:

# vif-openvswitch (add|remove|online|offline)
|

#
|
||||
# Environment vars:
|
||||
# vif vif interface name (required).

# XENBUS_PATH path to this device's details in the XenStore (required).
|
||||
#
|

# Read from the store:
|

# bridge bridge to add the vif to (optional). Defaults to searching for the
|
||||
# bridge itself.
|

#
|

# up:
|
||||
# Enslaves the vif interface to the bridge.
|
||||
#
|

# down:

# Removes the vif interface from the bridge.
