I would like to know how much memory and cpu virtual machine are using so yes guest's perspective. I'm building a web app that has to alert the user when the vm is going to be stressed and I would like to do this in terms of mem and cpu usage.
Thanks in advance for your support,

resources has the host given to the guest) or from the guest's
perspective (how much is the guest actively using, even if the host has
given it more)? Libvirt already provides several API calls. such as the
ones used by 'virsh cpu-stats' and 'virsh dommemstat'; you may have to
do some code reading to figure out what C calls the virsh code made in
order to find the same API under the Java bindings.
