I've used
http://resources.ovirt.org/pub/ovirt-3.6/iso/oVirt-toolsSetup/3.6-3/oVirt-toolsSetup_3.6-3.fc23.iso
But also, i've compiled ovirt guest agent from sources from github and had
the same result.

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.
Can you please give me the exact version of the ISO you’re using?
I need to determine if you have the fixed one or if there’s another bug, the
latest version should have this fixed already.

You probably don’t have the virtio drivers for the channel
communication installed
please install the VirtIO Console drivers on that machine and
restart the agent service
If hypervisor opens ovirt socket, then cpu usage drops to normal
state.
Is this intentional? This does not happen on Linux guest.

Hello groups,
we are having problem with ovirt-guest agent on Windows os.
When
started, agent fully utilizes one core (if machine has single
core,
then you will see 100% CPU usage, if there are two cores, then
you
will
get 50% usage etc). Usage does not drop and persists for a
whole
time
ovirt agent is running. This happens on windows 7 32 and 64
versions
and also on windows 10. Have anybody had the same issue?
Thank you.
