Overview

Handler for ‘pvectl get node-capabilities`.

Surfaces what features a node supports — primarily the available QEMU CPU models and machine types. When ‘–node` is provided the query is scoped to that node; otherwise the handler iterates all online nodes and aggregates the results, silently skipping unreachable nodes (matches the pattern used by the time handler).
