Do you mean something like this ?
/usr/share/ovirt-engine/dbscripts/engine-psql.sh -c "select disk_id,image_guid,disk_alias,disk_profile_name from all_disks where disk_content_type='0' order by disk_alias" > /root/disk_ids-to_vms.txt
partially, because in my case if I take a VM with VM ID 711e5dc6-04a1-42a4-b52c-96685bc19b1f
It has 3 disks, one of which has the alias ostack-ceph1_Disk3
the query for this disk gives
select disk_id,image_guid,disk_alias,disk_profile_name from all_disks where disk_content_type='0' order by disk_alias;
. . .

And I get under /2t_1

but I miss the link between the id of the VM and the disk, that is what I would like to get
