Unfortunately I can't offer much advice on why it happens, but increasing log verbosity may help troubleshoot it. These are the relevant lines I use in /etc/libvirt/libvirtd.conf log_level = 2 log_filters="2:remote 2:event" log_outputs="2:file:/var/log/libvirt/libvirtd.log" Be careful with level 1 alerts...I generated a 100GB text log in 3 days. To fix that problem and unlock a VM, you need to kill libvirt, remove the PID files and start libvirt # service libvirtd stop # rm -rfv /var/run/libvirt # service libvirtd start More information here, https://bugzilla.redhat.com/show_bug.cgi?id=676205 - Trey
