Hi, everyone, My hypervisor is kvm, when I use libvirt-java api to get guest vm memory information, I found what libvirt can not get real memory(within the vm)statistic, libvirt can only get information from .xml file(such as vmName.xml <currentMemory> lable) in host. My question is, does libvirt support memory monitor(within vm)? if it's true, how to get. if false, what is the difficulty?
I'm not sure what exactly you mean by memory monitor within vm. You can communicate with your own program in the VM and gather statistics there. Or I might've misunderstood your question and you might find virDomainMemoryStats() API helpful. HTH, Martin
Thank you. frankpersist@xxxxxxxxx
