Currently, building the NEWS file involves using a XSLT stylesheet to extract information from the same HTML file that's used on the libvirt website. The process works, but it's quite fiddly in that it requires the source HTML to be formatted in a very precise way, and a single missing newline can mess up the resulting plain text considerably. Moreover, the XSLT stylesheet itself encodes a lot of the details of converting to plain text in a way that's not necessarily easy to understand, tweak or fix. To improve the process, move all existing entries to a new XML file that contains exactly the information we care about in a simple structured format, and start generating both the HTML and plain text versions of the release notes using XSLT stylesheets that can now afford to be almost trivial.

of the release notes.

Keep the style consistent with existing entries as much as possible:

each change should be documented by a short, one-sentence summary

qemu: Use virtio-pci by default for aarch64 mach-virt guests

</summary>
|
|
<description>
|
|
virtio-pci provides several advantages over virtio-mmio, such
|
|
as the ability to hotplug devices and improved performance.
|
|
While opting in to virtio-pci has been possible for a while,
|
|
newly-defined guests will now use it automatically

device that is an Express device (all virtio-1.0 devices,

e1000e, nec-xhci, vfio assigned devices) will be placed on
|
|
an Express controller (i.e. a pcie-root-port) instead of a
|
|
legacy PCI controller (i.e. pci-bridge) with the root ports
|
|
added as needed
