[Koha] Koha as a Virtual Machine on ESXi - Failed to open disk scsi0:0: Unsupported or invalid disk type 7

[ISM KIS]

We have Koha 3.0.4 running at our school and I thought I could play with 3.2 on our brand new virtual host.

Here is what I did:
Downloaded the VM from http://kylehall.info/index.php/projects/koha/koha-virtual-appliance/
ESXi 4.1 is running and  the files are uploaded to the datastore.
.vmx is added to the Inventory

But when I start the VM I'm getting the following error:
   Module DevicePowerOn power on failed. 
   Unable to create virtual SCSI device for scsi0:0, '/vmfs/volumes/4d0f....
   Failed to open disk scsi0:0: Unsupported or invalid disk type 7. Make sure that the disk has been imported.

Is there a step I'm missing? Or are those files not for ESXi ??

(I was able to use the files on VirtualBox on my local PC)

Thanks for your help and happy holidays!
