Yes..I am running Ovirt 3.4 but still didn't find the scripts on the location :-
[root@cloud-mgmt dbscripts]# sh engine-psql.sh -c "select vm_name, image_group_id,image_guid from vm_device, vm_static,images where vm_name in('CentOS') and vm_device.type='disk' and vm_device.device='disk' and vm_device.vm_id=vm_static.vm_guid and images.image_group_id=vm_device.device_id order by vm_name ;"
sh: engine-psql.sh: No such file or directory
[root@cloud-mgmt dbscripts]# pwd
/usr/share/ovirt-engine/dbscripts
[root@cloud-mgmt dbscripts]#
