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.
6:21 a.m.
It seems, that if socket is not opened at hypervisor side, ovirt agent
starts to loop with loads of "VirtIoCHannel::200::root::Written"
messages per second.
If hypervisor opens ovirt socket, then cpu usage drops to normal state.
Is this intentional? This does not happen on Linux guest.

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

"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.

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

I need to determine if you have the fixed one or if there’s another bug, the latest
version should have this fixed already.

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? Are you sure that it doesn’t execute the other
one?

I will try to compile it again. I've installed via ovirt commandline
"OVirtGuestService.exe -install". Maybe i've managed to put wrong daemon.
Will try this again.
