I got an OMV server that is also running a VM of Linux mint with virtualbox. Though it runs kinda slow due to it being stuck in software mode for display. I threw in a cheap nvidia GPU just to help in assisting with rendering. However that's easier said than done. I'm not necessarily looking for a direct passthrough per say; even being able to check use 3D acceleration option in virtualbox would be great. Also i know the card at least is working at a hardware lever as the console will display through the card, but not sure if OMV is even able to recognize it at all or not. If anyone is aware of how this could be done that would be great. I've been searching for a solution with not much luck. Thanks to anyone who may be able to help.
For hardware FYI of my OMV server:
i3 4 core
Nvidia GeForce 710
