Hello,
I'm trying to get memory usage statistic inside a guest machine using
virDomainMemoryStats function at libvirt.
According to
http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStatTags the
structure could have a lot of useful memory statistic but the amount of
parameters depends on the hypervisor and the driver.
However using KVM I'm able to get VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON
and VIR_DOMAIN_MEMORY_STAT_RSS only.
QEMU/KVM only supports these two IIRC.
Am I right it is not possible to get additional info such as
used/unused
memory inside a guest machine in case of KVM?
Yes. Actually reporting some data from *inside* the domain is not
what libvirt aims to provide.
