MCS - An error occurred while preparing the image . A specified parameter was not correct: deviceChange[1].device.key



Trying to do an MCS and getting these errors.  Also tried making a snapshot through VMWare and using that to update the images and still getting the same error. Anyone run into this or have any suggestions?

Hi, I am having the same error since we upgraded to vmware 7.0 Does someone have an idea ?

On the vmware forum here is the answer I received:

To fix the issue, you need to make sure that all of the devices that you are trying to add to the VM have unique device keys. You can do this by generating a new device key for each device Thank you in advance for your help
