[Libvirt-cim] [PATCH] (#2) Fix MemoryPool.Reserved to show only actively allocated memory
# HG changeset patch # User Chip Vincent <cvincent@us.ibm.com> # Date 1308756569 14400 # Node ID c5a9510b6bd1569c6ab0966624306e29ecd81727 # Parent 6c29c5b284443e226e7d97e7e5f11848b0c4e761 (#2) Fix MemoryPool.Reserved to show only actively allocated memory.
It appears Reserved is meant to show memory that is taken (actively in use by VMs) as opposed to memory that is potentially taken (assigned to defined, but not running VMs). Also added CurrentlyConsumedResource (a much clearer name for the same thing) and ConsumedResourceUnits, fixed units to conform with DSP1045, and cleaned up some extraneous whitespace.
Changes from #1: - Fix return code checking
