So long as this new VM memory RASD AllocationUnits ("byte*2^10") will
match that of the MemoryPool capabilities' RASDs, and the new 'augmented
BNF' string is parsed ok when passed as an embedded instance to the cimom
(pegasus, sfcb) then I'm okay with this one-off too. Both these are
required otherwise existing usecases will break.

We do have a schema update planned for this year. I think the origianl
plan was just to update the schema but perhaps we should rebase some of
the profiles as a follow on. If everyone agrees we should rebase the
profiles as part of the schema update, then I'm okay with this as a
'one-off' change for now.
Comments?

If we're doing this sorta change here then we should probably do it
everywhere, since users may be checking AllocationUnits between CIM
classes. Specifically, these should match the units being returned from
memory pool capabilities, and we need to check these new units will be
correctly parsed when passed as embedded instances (eg DefineSystem(),
ModifyResourceSettings(), etc)... Alternatively, we might want to
consider going thru the entire libvirt-cim suite and upgrading all
classes from DSP0004v2.4 to DSP0004 2.5+ conformance level (ie using
Augmented BNFeverywhere its relevant) rather than having in old and new
units sprinkled around.
Basically, doing this change here and now may have much wider
implications.

changed a bit to make it conform to CIM profile
According to the discuss and profile, the reserved property means the
memory actually allocated to support the VM running, and the unit
should be byte*2^10. This patch added some code to retrieve VM's state,
and the report the memory status according to that.
