February 20, 201610 yr Okay, so as the title says: Before I dive into the world of unRAID, I have a few questions. Here goes. 1. Would I be able to pass one gpu through to two virtual machines, or just one? 2. With AMD (graphics) cards, can you use it for the unRAID OS and a guest OS? 3. CPU assignment is based off of cores, correct? (So if I had 2x 8 core Xeons and 4 vms, I could assign 4 cores to each vm?) 4. Internet connection- most motherboards have only one or two ethernet ports- I take it all the VMs would run off of the same ethernet port? Or would I need a NIC? After searching google for a few hours I couldn't find any of these answers... And I just want to figure this all out before taking the plunge. Thanks, all!
February 20, 201610 yr Author Oh yes, and a final one: With storage, would I partition off the drive into 5 partitions for 4 vms (One for the unRAID OS) or is that not necessary?

The entire system is stored on a Flash Drive and runs entirely from RAM. Certain configuration files which are contain information on the exact configuration of your server are also stored on that Flash Drive. Once, you have your system configured, there are very few writes back to the Flash Drive so the read/write speed of the flash drive are not a factor in server performance. While I am not expert on VM's, I do believe that most people store all of the configuration and system files for their Vm's (and Docker containers) on the cache drive, not the array. You might want to look at some of the videos on setting unRAID systems here: https://lime-technology.com/videos/ There are a couple that are directly related to your questions about VM's.

I found most of what I needed in the videos. However, my last question is the one about the GPU passing-through. I couldn't seem to find anything on that.
February 21, 201610 yr Sorry, I just don't have any good knowledge/advice on GPU pass through as there are several factors involved for it to work. What I would suggest doing is modifying the title of this thread to something like: A Few Questions about GPU Pass Through
February 21, 201610 yr I believe you can only currently pass one GPU through to one VM, you could configure the second to use VNC, or a second physical GPU.
