The fact is that today we return guest information in list(Full=true), We decide on it's notion and it seems like we already made our minds when guest info was added there :) . I don't see any harm in returning the disk mapping there and if we'll want to extract the guest info out, we can extract all of it in later version (4?) without need for BC. Having the information spread between different verbs is no better imo. > > At first sight this seems something belonging to getVmStats (which > is reporting already other guest agent information). > Fede, I've mentioned in the wiki, getVmStats is called by the engine every few seconds and therefore that info wasn't added there but to list() which is called only when the hash is changed. If everyone is in for that simple solution i'm fine with that, but Michal/Vincenz preferred it that way.
