libvirt is an important piece of the overall open source virtualization management puzzle. Many of the open source virtualization management applications that users enjoy are based on libvirt, since it provides a normalized API for managing heterogeneous hypervisors. For Xen to enjoy this greater ecosystem of open source virtualization tools, it must be well supported and maintained in libvirt. This presentation will give a basic overview of libvirt, discuss the latest status of the libvirt libxenlight driver (also known as the libxl driver), and discuss future improvements planned for the driver.
