Well this one has not the fixed issue > But also, i've compiled ovirt guest agent from sources from github and had > the same result. The github version starting from March 15th 2016 (master / ovirt-4.0 / ovirt-3.6 branches) should actually not cause 100% CPU usage since there’s a sleep in case of an error, which seems to be happening here. So you installed and started it how then?
