Hello,_______________________________________________
I am trying to execute virsh commands on a host but it is giving errors
due to failure in acquiring lock.
root@kvm01:~# virsh suspend blindone
error: Failed to suspend domain blindone
error: Timed out during operation: cannot acquire state change lock
Any suggestions how can we figure out possible reasons.

I've run into this a few times when a snapshot hangs. 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
