i have a GTX 690, and i want to pass one of the gpu's through to a VM, and use one of them for the host. can i do that?

Is this for VMware Workstation/Player, or through ESXi?

nope. 

skip to 8:52. that gives you an idea of what i want to do, but use Linux for both the host and the VM.

@TopHatProductions115 what i don't know is if it groups both gpu's into 1 IOMMU group, that's my problem.

What distro? Is it the workstation in your signature with Manjaro? What hypervisor?

 

Here is an article for arch on PCI passthrough via OVMF

i know that. that goes for using a seperate card in a seperate pci-e slot. i'm using a dual-gpu card, and i want to pass through one of the gpu's on that card.

I don't know for sure, but I really doubt that is possible. Maybe I am totally wrong, but are they individually addressable cards? Or are they shown as a single card? If single, I don't think its going to work the way you want. But I have no experience in that so I can't say for sure, I just know pass through with VT-d in ESXi with HBA's and such.

you can use both gpu's seperately, one of the dvi outputs is wired into the second gpu.

Yea, I guess on second thought that makes sense. Has to show as 2 cards to enable SLI I suppose...

But, still, does it show up as a single PCIe Device tho? Hmm. I am not sure if those things are mutually elusive or not, nor if that would impact what your trying to do. I guess my question is, is this known to be possible? If so, yea I have no idea man, sorry.
