Re: [libvirt PATCH v3 0/8] Make unknown XML elements fail CPU comparison

We currently ignore unknown elements in the CPU XML description, e.g. with virsh cpu-compare and hypervisor-cpu-compare. This makes '<cpu><faeture name="..."/></cpu>' (note the typo in "faeture") semantically identic to '<cpu/>'. No error is reported. This series adds checks for unrecognized attributes and elements in the "<cpu>" element, catching this kind of mistake. V1: https://www.redhat.com/archives/libvir-list/2020-September/msg00933.html V2: https://www.redhat.com/archives/libvir-list/2020-September/msg01073.html Changed: * Added more detailed commit messages * Added missing man page details * Split the changes slightly differently in the commits * CPU tests now always validate XML documents * Fixed typo "nonexistant" -> "nonexistent" Tim Wiederhake (8): schema: Unify apostrophe and quotation mark usage schema: Move host cpu definition to cputypes.rng schema: Move guest cpu definition to cputypes.rng schema: Add schema for guest or host cpu definition util: Allow validation for single XML node

cpu: Wire in XML validation virsh: Add "validate" argument to [hypervisor-]cpu-compare tests: Add tests for unknown elements and attributes in cpu defintion
