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.

Searching the project , I do find another place using the old string: Virt_SettingsDefineCapabilities.c:354: CMSetProperty(inst, "AllocationUnits", (CMPIValue *)"KiloBytes", CMPI_chars); After this is changed, I thought the libvirt-cim would have no more "KiloBytes". But I don't understand the BNF' string you refered, could u give more tips about that?

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.

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. https://bugzilla.linux.ibm.com/show_bug.cgi?id=72759
