These fields are supported by libvirt, but unfortunately qemu has
disabled them for monitor command query-ballon for a critical bug,
it has been for a long time. I'm not clear about how the current
status is, though I guess it's still not enabled.
Is that only for the VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON or for all the
counters ? Should i ask about the monitor command query-balloon on the qemu
list ? Do you have details of the critical bug ?
The version of libvirt 0.9.11 on
