RHEV: Can't connect to virtual machine consoles, and qemu shows high CPU usage

Solution Unverified - Updated -


  • VM show "host not responding"
  • Connection to VM console through the user portal stops at the 'connected to graphic server' screen
  • One thread of a qemu process shows 100% load
  • VMs can show a CPU load in the 60%-70% range, although the guest is idle
  • Restarting VMs does not correct the problem


  • Red Hat Enterprise Virtualization 3.2
  • spice-server-0.12.4-6.el6.x86_64
