Works for me,
but I need to send a stats-polling-interval != from the start
stats-polling-interval
(maybe it's not resend to the balloon driver if the value is equal)
Don't know why balloon device works differently on windows, but it seem to get
the stats-polling-interval value, only when windows is fully started.
working (started with interval=2)
--------------------------------
(QEMU) qom-get path=/machine/peripheral/balloon0 property=stats-polling-interval
{u'return': 2}
(QEMU) qom-get path=/machine/peripheral/balloon0 property=stat-free-memory
{u'error': {u'class': u'GenericError', u'desc': u"timer hasn't been enabled or
guest doesn't support 'stat-free-memory'"}}
(QEMU) qom-set path=/machine/peripheral/balloon0
property=stats-polling-interval value=3
{u'return': {}}
(QEMU) qom-get path=/machine/peripheral/balloon0 property=stat-free-memory
{u'return': 1765240832}
non working (started with interval=2)
------------------------------------
(QEMU) qom-get path=/machine/peripheral/balloon0 property=stats-polling-interval
{u'return': 2}
(QEMU) qom-get path=/machine/peripheral/balloon0 property=stat-free-memory
{u'error': {u'class': u'GenericError', u'desc': u"timer hasn't been enabled or
guest doesn't support 'stat-free-memory'"}}
(QEMU) qom-set path=/machine/peripheral/balloon0
property=stats-polling-interval value=2
{u'return': {}}
(QEMU) qom-get path=/machine/peripheral/balloon0 property=stat-free-memory
{u'error': {u'class': u'GenericError', u'desc': u"timer hasn't been enabled or
guest doesn't support 'stat-free-memory'"}}
