Thanks  dbaxps 
files has correct permissions

Found solution for this 
As i was using root privileges
I need to change the below mentioned in qemu.conf 
to get permissions for launching VM 

Change the file in  both controller and compute 
     vi /etc/libvirt/qemu.conf 
     #user = root  -> user = root 
     #group = "root" - > group = "root" 

now restart libvirtd service 
     systemctl restart libvirtd.service
