Re: [ovirt-users] ovirt-Guest-agent CPU usage
"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.

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
