Description of problem: When describing the features of libvirt, the libvirt doc uses implicit words like "some, almost". For example: https://libvirt.org/formatdomain.html Note that the vhost server replaces both the disk frontend and backend thus almost all of the disk properties can't be configured via the <disk> XML for this disk type. Here we should say which properties are supported and which are not.
This is way too generic BZ. We basically should improve the whole libvirt XML documentation and that is not downstream material. I've created an upstream issue to track this https://gitlab.com/libvirt/libvirt/-/issues/134 and will close this BZ.
