A year has passed since the last Xen Developer Summit and it is time to announce the quiet progress made on the libvirt libxl driver and related tooling. New features include memory, cpu, block device, and network interface statistics reporting, support for pvUSB, support for migration stream V2, peer-to-peer migration, UEFI for HVM guests via OVMF, and domain capabilities reporting to name a few. There are also many noteworthy improvements such as better conversion of xl.cfg to/from libvirt domXML, allowing users to easily switch between the xl+libxl and libvirt+libxl toolstacks.
The summit also provides an opportunity to discuss new proposals such as better control of domain placement on NUMA systems, exposing Xen's cpu pool feature in libvirt, supporting non-volatile memory for UEFI variables, and improved capabilities reporting.
Much of libvirt's value for Xen is in the tools built upon it: virt-manager, virt-viewer, virt-install, virt-builder, kimchi, OpenStack nova, etc. These tools also deserve a quick status update as they relate to Xen.
The audience is encouraged to participate, e.g. by requesting a sorely missing feature, warning of an upcoming Xen change that may affect libvirt, or simply suggesting a change that makes virtualization management life a bit easier.
