[pve-devel] pve-manager : expose balloon to gui

[Alexandre DERUMIER]

I have just redone tests on my win2003, with last pve-qemu-kvm, it doesn't work anymore ....

(QEMU) qom-get path=/machine/peripheral/balloon0 property=stats-polling-interval
{u'return': 0}
(QEMU) qom-set path=/machine/peripheral/balloon0 property=stats-polling-interval value=10
{u'return': {}}
(QEMU) qom-get path=/machine/peripheral/balloon0 property=stats-polling-interval
{u'return': 10}
(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-get path=/machine/peripheral/balloon0 property=stats-last-update
{u'return': 1355842494}
(QEMU) qom-get path=/machine/peripheral/balloon0 property=stat-total-memory
{u'error': {u'class': u'GenericError', u'desc': u"timer hasn't been enabled or guest doesn't support 'stat-total-memory'"}}
(QEMU) 


...

it was working fine with qemu 1.3 + 2 firsts balloon stats patchs from qemu mailing.

Maybe something have changed ?

I'll do some tests with win2008. 

(I was also sending stats-polling-interval each second with pvestatd because I didn't work at start, but I think you have corrected that) 


Does manual balloning work ? Is it only a stats problem ?

I tested with w2008r2 and win8 - but I can't get that to work. 

balloon driver is loaded, and blnsrv is running - but no stats :-/
