Capabilities are sets of bits that permit of splitting the privileges typically held by the root user into a larger set of more specific privileges. The POSIX capabilities are defined by a draft IEEE standard (IEEE Std 1003.1e); they are not unique to Linux or Virtuozzo. When the Linux or Virtuozzo documentation says "requires root privileges", in nearly all cases it really means "requires a specific capability".
This section documents the tasks that can be achieved using per-container capabilities in Virtuozzo and all configurable capabilities.
