Hi everybody,

I'm using libvirt java api bindings for my thesis. I would like to know if there is a way to obtain live information about cpu and mem usage of a domain.

Are you asking the question from the host's perspective (how much 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. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
