No sir, @Ali Amir I was never able to successfully work through this. I was able to get a Windows 10 VM to brief support the same/similar (single Quadro 2000 -- my Cisco rack server has three of these installed in it, perfect for VDI deployment) in a custom HPE 6.7 ESXi build, but that only lasted until I rebooted the VM, now I'm getting the entire host hanging and other odd behaviors. If I wait a very long time, the machine finally comes up and I can access it remotely, but if you were to stand there locally and watch the screen, the progress bar gets stuck and never appears to finish loading.
Trying to update firmware on my C240-M3S to latest version 3.0(4j) and hopefully try again with CISCO Custom Image for ESXi 6.7 U1 GA. Will keep you posted if I make any progress, sir. Please do the same if you have found a resolution. Hate having three GPUs in this machine taking up space and wasting electricity with no ability to properly utilize them. I know they are working find, as I booted the machine into Windows and was able to apply drivers and test all three cards independently, so it's definitely an issue with either VMware's product, or more likely, my configuration.
EDIT: I can tell you that simply rebooting the host resolves the "catastrophic" failure, but boy that certainly scared me the first time I saw it come up and wasn't sure what I had done, if I had truly messed up. Thankfully it was just related to the PCI Passthrough. Will be looking to invest some time in the coming days/weeks to hopefully give it another go and see if we can work around the issue.
There was this thread that I attempted to refer to, it seemed to have significantly more information than anyone around here was able to provide: https://forums.servethehome.com/index.php?threads/troubleshooting-gpu-passthrough-esxi-6-5.12631/
