##### SUMMARY
<!-- Explain the problem/feature briefly -->
By default ,we cannot get the memory usage of vm through libvirt;
Through analysis, it is found that the reason is that we did not add
memballoon correctly in kvm;
When the mem.overprovisioning.factor of the cluster <= 1.0, kvm will
generate the following memballoon
<memballoon model='none'/>
When the mem.overprovisioning.factor of the cluster is > 1.0, kvm will
generate the following memballoon
<memballoon model='virtio'/>
So when memballoon.model=none, we can't get the memory usage of the vm
through dommemstat (assuming they all have qga installed correctly)
I wonder if we can set memballoon to virtio under any circumstances, and
configure period=10 to let it automatically count the latest memory consumption.
In this way, we can use third-party tools to monitor the resource usage of
the vm, making up for the regret that cloudstack cannot view the historical
consumption of vm resources!
