Description Dan Callaghan 2011-10-20 03:36:39 UTC

When running on a KVM guest with memory balloooning, the /distribution/inventory task reports the current amount of memory allocated, not the maximum balloon amount permitted (which would be more useful for our purposes).

For example, when a guest has an initial allocation of 1GB and a maximum of 2GB, the memory amount is reported as 983 MB (1GB minus various reservations).

Comment 1 Dan Callaghan 2011-10-20 03:36:52 UTC

It seems lshw is able to figure out the true maximum balloon amount:

     *-memory
          description: System Memory
          physical id: 1000
          size: 2GiB
          capacity: 2GiB
        *-bank
             description: DIMM RAM
             physical id: 0
             slot: DIMM 0
             size: 2GiB
             width: 64 bits
