blog.scottlow.org Installing KVM and Open vSwitch on Ubuntu “This is the first of a number of posts in which I’ll be discussing Ubuntu Linux, KVM, and the Open vSwitch (OVS).”
Silicon Loons Virtual Machines on Fedora 17 with Open vSwitch My previous blog post showed you how to setup Open vSwitch (including LACP port-channels) on your Fedora 17 host. Once you have this working, creating virtual machines and adding them to one of your Open vSwitch bridges is the next logical step. For this setup, we will make use of libvirt to manage our virtual machines. We’ll utilize virt-manager (a GUI) and virsh (a CLI) to manage the VMs on the host. But the VMs themselves, once running on Fedora with libvirt and KVM, can easily be migrated into an oVirt setup, for instance.
Silicon Loons Fedora 17 with Open vSwitch Good explanation on how to setup Open vSwitch with LACP port-channels on Fedora 17.
Linux-KVM Using Open vswitch with Fedora 17 “The recently released Fedora 17 comes with improved support for open vswitch. It includes packages for installing open vswitch as well as libvirt support for managing open vswitch under KVM. Open vswitch is an interesting project providing a multilayer software switch that provides enterprise grade virtual switching technology and the emerging and popular openflow protocol for managing networks.”

Rainmakers Nicira and Citrix Promote Open vSwitch for Open Network Virtualization “This week we’ve been looking at the Open Source Open vSwitch, which comes as part of Linux 3.3 distributions such as Ubuntu, Debian and Fedora. It’s essentially a hypervisor-networking stack used for automated and dynamic networking control in large-scale Linux-based virtual environments.”
NetworkStatic Configuring VXLan and GRE tunnels on OpenvSwitch “I have done a couple of GRE tunnel how-tos using OpenvSwitch (OVS). I ran across the git tree of the VXlan implementation which is still in development I am sure. I don’t want anyone to think this is anything other than me seeing the tree on GitHub. I had been itching to give VXLan a spin in OVS so why not ferret out someones tree on GitHub. I believe VXLan is still scheduled to officially release soon in OpenvSwitch.”
One Unified Installing Open vSwitch on Debian Sid/Wheezy “Open vSwitch appears to be the up and coming mechanism for connecting virtual guests to the physical network through bridges, vlans, and network cards.”

S3hh’s Blog Connecting containers on several hosts with Open vSwitch ”Lxc is great for starting up several containers on your laptop or on an ec2 host. But what if you want to fire up containers on multiple ec2 instances, and have them talk to each other? An easy way to support that is using openvswitch.”

IT From All Angles Linux-KVM: Ubuntu 12.04 with Openvswitch ”Openvswitch is a better way of managing your virtual networking stacks for KVM and Xen. This can be used instead of the bridge-utils package, and has the ability to use VLANs, LACP, QoS, sFlow, and others. In this article we will be using Ubuntu 12.04 (beta1) to configure Openvswitch to hand out networking interfaces to KVM guests.”

InternetNews The Beefy Miracle Begins. Fedora 17 Hits Alpha 1 ”On the virtualization front, Fedora is including Open vSwitch which is a virtual switch project that plays a critical role in the OpenStack Quantum networking module. OpenStack is an open stack cloud effort that Red Hat has some involvement with and the embrace of Open vSwitch in Fedora is a huge step in my opinion. It means that the Fedora community will get to test out and use this virtual switch making the path to OpenStack Quantum for Fedora users, relatively easy. OpenStack Essex (the upcoming release) is also set for inclusion in Fedora 17 as is the full Quantum stack.”
