[Qemu-devel] qmp query-balloon return only "actual" value ?

[Alexandre DERUMIER]

Hi,
I'm trying to use qmp "query-balloon", to get stats,

>From Doc, I expect to have


-> { "execute": "query-balloon" }
<- {
      "return":{
         "actual":1073741824,
         "mem_swapped_in":0,
         "mem_swapped_out":0,
         "major_page_faults":142,
         "minor_page_faults":239245,
         "free_mem":1014185984,
         "total_mem":1044668416
      }
   }


But I got only

-> { "execute": "query-balloon" }
<- {
      "return":{
         "actual":1073741824,
      }
   }


qemu 1.3.

Guest kernels tested : 2.6.32, 3.2 and 3.5.

Does I need a more recent kernel in my guest ?

Regards,

Alexandre
