The latest libvirt release is out!

If you read the libvirt development mailing list, you will have noticed that libvirt released 2 versions this week, the latest of which is version 0.10.1. This version includes a bunch of bug fixes, but between this and the previous 0.10.0, there are some changes in how you work with Open vSwitch virtualport types. I thought I’d explain some of them here, as they are advantageous and will make deploying libvirt with Open vSwitch easier.

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.

Fedora 17 with Open vSwitch

I’ve recently decided to move some of the virtual infrastructure in my lab onto Fedora 17.

But for now, I plan to simply make use of a combination of virsh and virt-manager.

Open vSwitch Kernel Code Moves Upstream

Just a note that over the weekend, after a few weeks of reviews, the Open vSwitch Kernel Code has moved upstream. Dave Miller pulled the code this weekend. Getting this upstream will be really helpful for OpenStack Quantum, as the default plugin for that code uses OVS. This is also great for distributions who want to include OVS, but have been hesitant because of it’s lack of existence in the upstream kernel.
