Yes, a generalized VMware Templates is not supported. It currently prevents the version of the VMware SDK we use to successfully mount the image to process the scan/deployment. We are upgrading the VMware SDK in Protect 9.2 and although not tested, it is 'possible' it may work. I believe one our QA engineers will be testing the sysprep area soon and I will request tests with Generalized enabled. No ETA, but soon.
I will post an update once I have one.
After testing, we can confirm the Generalized option is still not support. The image mounting fails because the VDDK is unable to determine what the system drive is (because the image is generalized to be hardware independent). We need this information to load the registry files for scanning/deploying.
Let me know if you have any questions.
