Abstract
The Xen hypervisor is a Open Source Type 1 hypervisor, it's widely used on production environments like Amazon EC2 and Rackspace. Since it's inception, one of the focuses of Xen was to be an OS agnostic hypervisor, allowing any kind of OS (with proper Xen support) to act as DomU/Dom0. This talk will cover how the Xen community works, together with an explanation of the ongoing work in FreeBSD in order to improve Xen support. This talk will cover the following points: Basic Xen description and specific Xen concepts. How the Xen community works (compared to BSD communities). A look into new Xen features (PVH). Work being done in FreeBSD improving Xen support. Probably a small demo to highlight Xen features.
