Sorry, managed to send corrupted message.
I do not think there's problems with virtio console drivers. I've installed ovirt guest tools iso from http://resources.ovirt.org/pub. Also I can read data from ovirt agent on hypervisor side by using socat: "socat pathtosocketfile -" This gives me all information about VM from ovirtagent. But as soon as i close reading socket, ovirt agent loops in itself and uses whole single core. If i socat again - load drops and I can see information from agent again. So problem is that you allways need to have socket open for read or write on hypervisor side. If not - ovirt agent will consume one cpu thread. And this happens only in Windows VM.
