...d is some kind of bug related to CPU feature reporting. I'm not really interested what is the reason of the message (I'm sure it will be fixed in an upcoming release), but I would like to get rid of these annoying messages libvirtd[1319]: internal error: unable to execute QEMU command 'qom-get': guest hasn't updated any stats yet do you have any idea? Thank you L:

...virDomainMemoryStats exactly. > > Which OS are you using in your guests? > > Of course, you need to have the virtio balloon driver up and runnig in > your guests. You also have to have new enough qemu that reports stats without blocking (qemu 0.14 or newer added stat reporting via qom-get, since the older query-balloon interface blocks) and libvirt that knows how to read stats via qom-get (libvirt 1.1.1 or newer). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
