[pve-devel] Baloon Device is the problem! Re: migration problems since qemu 1.3

[Alexandre DERUMIER]

does it work if you keep device virtio-balloon enabled,

but comment in qemuserver.pm

line 3005
vm_mon_cmd_nocheck($vmid, 'qom-set',
                       path => "machine/peripheral/balloon0",
                       property => "stats-polling-interval",
                       value => 2);


and

line2081
 $qmpclient->queue_cmd($vmid, $ballooncb, 'query-balloon');

?

maybe it's related to qmp queries to balloon driver (for stats) during migration ?
