Generally, it means your qemu returns empty result for
monitor command query-balloon. Could you check the debug
log to find out what the qemu monitor command returns
actually?
libvirt > 0.9.4 memStats() can get the memory stats,but it seems that
the
value does not match guest memory usage:
virsh # version
Compiled against library: libvir 0.9.11
Using library: libvir 0.9.11
Using API: QEMU 0.9.11
Running hypervisor: QEMU 1.0.94
virsh # dommemstat centos
actual 524288
rss 276252
while in the 'centos' guest:
[root@centos-guest ~]# free -k
total used free shared buffers cached
Mem: 511148 84784 426364 0 5708 32664
-/+ buffers/cache: 46412 464736
Swap: 2064376 0 2064376
what does the 'rss' mean? thanks.
