Few questions: 1. Were there any other Storage Domain which are not present in the setup? In the original RHEV instance - there were 3 storage domain i) Hosted engine storage domain: engine ii) Master data domain: vmstore iii) An export domain: expVol (no data here) To my backup RHEV server, I only imported vmstore.

2. Can you look for the image id 6f4da17a-05a2-4d77-8091-d2fca3bbea1c in your storage server (Search on all the rest of the storage domains)? No - there was no file with this id (checked both in the original RHEV instance) [root@dhcp42-105 mnt]# pwd /rhev/data-center/mnt [root@dhcp42-105 mnt]# find . -name 6f4da17a-05a2-4d77-8091-d2fca3bbea1c [root@dhcp42-105 mnt]#

Were there any operations being done on the VM before the recovery such as remove disk, move disk, or a new creation of a disk? No. The only operation done was creation of a snapshot - and it completed before the recovery was attempted.
