##### OS / ENVIRONMENT
VMware hypervisor
##### SUMMARY
VM deployment fails as the mapping of the disks fails. The order of the
disks as described in the OVF file as shown above differs from the order
retrieved by VMware (as also shown in the picture below):
The mismatch on the ordering of disks leads to the following:

##### STEPS TO REPRODUCE
~~~
- Register a template with different controller types for example one per
disk and select the option 'Read VM settings from OVA'
- Create VM from template
- Start VM
~~~
##### EXPECTED RESULTS
~~~
VM is deployed and its state = Running
~~~
##### ACTUAL RESULTS
~~~
VM deployment fails
