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 postshowed 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 libvirtto 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.
