You also need to have this code hooked in:

cd /usr/libexec/vdsm/hooks/before_vm_start/

vi 99_mask_kvm

#!/usr/bin/python2

import hooking

domxml = hooking.read_domxml()

hyperv = domxml.getElementsByTagName('hyperv')[0]

smm = domxml.createElement('vendor_id')

smm.setAttribute('state', 'on')

smm.setAttribute('value', '1234567890ab')

hyperv.appendChild(smm)

features = domxml.getElementsByTagName('features')[0]

kvm = domxml.createElement('kvm')

hidden = domxml.createElement('hidden')

hidden.setAttribute('state', 'on')

kvm.appendChild(hidden)

features.appendChild(kvm)

hooking.write_domxml(domxml)

only problem now is that I cant boot a linux VM with the vendor_is portion there......

Seems that the system has to be running with bios Q35 UEFI. Standard bios does not work. System is operational now.

Still no luck getting the gtx 1080 to enable inside the VM. I see the code is being generated in the xml with the hook. But I still get error code 43. Someone mentioned doing it with eufi bios and that worked for them. So when I get back from work today, perhaps ill give that a try.

I have gotten the system to see the card, its in device manager. The problem seems to be that I cannot use it in the VM because from what I have been finding out is that it gets and error code 43. Nvidia drivers disable the card if it detects that its being used in a VM. I have found some code to use to hook it into the xml before_vm_starts.

I am currently reinstalling the drivers to see if this helps. 

kvm off and vender_id is now in the xml code that get generated when the VM is started. Im going off of examples Im finding online. Perhaps I just need to add the 10de to it instead of some generic # others are using.
