[ovirt-users] Guest CPU reported 100%

Hi all and Happy New Year! I have a ovirt 4.1.3.5 cluster (running with 3 nodes and shared gluster storage). I have randomly observed that some Windows 10 64bit VMs are reported from engine dashboard with 100%CPU while when connecting within the VM the CPU utilization is normal. Sometimes, when reported with 100% CPU I cannot get a console at VM (console gives black screen) then I have to force shutdown the VM and start it up again. The only warning I see is in the qemu logs of the guest reporting that CPUs not present in any NUMA nodes. Any ideas how to tackle this? Thanx, Alex
