Ended up fixing this by following the ovirt docs (go figure)

https://ovirt.org/develop/release-management/features/virt/hostdev-passthrough/

After following this I also had to reinstall my host as well as reboot.  The OS was not letting go of the device.

Strangely I have done this with two AMD graphics cards and they worked without this.  Perhaps the drivers weren't installed by default or something and the OS didn't have trouble passing it along.

Anyways, working happily now with my new quadro p2000 passed to a windows 10 guest. Makes a nice "desktop" at home.

I have recently been using an old Radeon R9 270X lying around without issue, until this card seemed to have kicked the bucket.

I had an Nvidia Quadro P2000 lying around I thought I would try.  After installing it into my system, it showed up in the PCI device as anticipated.  I based both devices to my Windows 10 guest.

It shows up a a GP106GL and a separate audio component.  The same thing that happened with the AMD Radeon Card.  The events just shows the VM's being terminated without giving a reason, and I am hoping for some guidance.  

Currently using a single node setup, running ovirt 4.2.3.  Any ideas or places to check would be much appreciated!
