Hi, all
I am trying to get used memory of a running vm using libvirt and then to
calculate the memory usage, but with no luck.
1.The used memory returned by virDomainGetInfo is equal to max memory with no
virtio balloon driver set. When using virtio balloon driver and setting
currentMemory less than memory in the xml, the used memory returned by
virDomainGetInfo is nearly equal to currentMemroy. Again, I can't get the
memory used by vm. 2. When I turned to virDomainMemoryStats, I can only get two
values : Current balloon value and Resident Set Size of the process running
the domain. (for kvm 0.14.1 and libvirt 1.0.2)
That's not what I want. I only need to know how much memory used by the
running vm, so I can calculate the memory usage of this vm. (like the used
memory return by cmd "free -m")
Any hints?
Many thanks!
