Hi, i've tried searching through the millions of GPU passthrough threads, but can't seem to find what i'm looking for.

 

I'm trying to pass through the 950 card through to a SEABIOS OSX VM. I've got the 1080 card working in windows fine. Am I misunderstanding something here? Does the numbers before the name when you do lspci correlate to the host in this qemu argument?

 

root@Tower:~# lspci -nn | grep NVIDIA

04:00.0 VGA compatible controller [0300]: NVIDIA Corporation GM206 [GeForce GTX 950] [10de:1402] (rev a1)

04:00.1 Audio device [0403]: NVIDIA Corporation Device [10de:0fba] (rev a1)

81:00.1 Audio device [0403]: NVIDIA Corporation Device [10de:10f0] (rev a1)

 

    <qemu:arg value='vfio-pci,host=04:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on'/>

    <qemu:arg value='-device'/>

    <qemu:arg value='vfio-pci,host=04:00.1,bus=root.1,addr=00.1'/>

 

I'm getting an error when attempting to start the VM:

internal error: process exited while connecting to monitor: 2016-10-05T05:32:17.636829Z qemu-system-x86_64: -cpu core2duo,vendor=GenuineIntel: Unknown protocol 'vfio-pci,host=04'

Edit this to remove the key.

 

Kevin.

cman9090 I replied in the other thread you posted  about this.

As I said in that one and digitalfixer says in this please please remove the apple osk key from your posts, just the mods will not like it. Just a heads up 

 

To get your passthough working.

1. remove this code you cant use vnc and passthough together.

  <input type='mouse' bus='ps2'/>
    <input type='keyboard' bus='ps2'/>
    <graphics type='vnc' port='-1' autoport='yes' websocket='-1' listen='0.0.0.0' keymap='en-us'>
      <listen type='address' address='0.0.0.0'/>
    </graphics>
    <video>
      <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/>
    </video>

 

then add this (put  in osk key!!)

  <qemu:commandline>
    <qemu:arg value='-device'/>
    <qemu:arg value='ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=2,chassis=1,id=root.1'/>
    <qemu:arg value='-device'/>
    <qemu:arg value='vfio-pci,host=04:00.0,bus=pcie.0,multifunction=on,x-vga=on'/>
    <qemu:arg value='-device'/>
    <qemu:arg value='vfio-pci,host=04:00.1,bus=pcie.0'/>
    <qemu:arg value='-device'/>
    <qemu:arg value='usb-kbd'/>
    <qemu:arg value='-device'/>
    <qemu:arg value='usb-mouse'/>
    <qemu:arg value='-device'/>
     <qemu:arg value='isa-applesmc,osk=put in your osk here !!!!!!!!!!!!!'/>
    <qemu:arg value='-cpu'/>
    <qemu:arg value='core2duo,vendor=GenuineIntel'/>
    <qemu:arg value='-smbios'/>
    <qemu:arg value='type=2'/>
  </qemu:commandline>

 

you didnt have  <qemu:arg value='-device'/>

    <qemu:arg value='ioh3420,bus=pcie.0,addr=1c.0,multifunction=on,port=2,chassis=1,id=root.1'/>

 

so were getting your error.
