Here is where you should mention what changed since v5, to help focus the attention of reviewers that have read earlier versions. > +++ b/qapi-schema.json > ## > +# @NumaDistOptions: > +# > +# Set the distance between 2 NUMA nodes. > +# > +# @src: source NUMA node. > +# > +# @dst: destination NUMA node. > +# > +# @val: NUMA distance from source node to destination node. > +# When a node is unreachable from another node, set the distance > +# between them to 255. Still no mention that distances less than 10 are invalid, or that a node to itself defaults to 10 and can't be changed, or that other distances default to 20. But that starts to get complex enough, and you cover it elsewhere, so I'm okay with what you have here. Interface looks sane, but I'll leave others to do the code review. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
