Not sure if this may help to add to syslinux video=efifb:off

how do you do this?

Click on the flash drive in Main tab and add to the syslinux config.

 

I tried this parameter however i cannot see the card on the peripherals list under Windows. 
 

i have to say i did not put the graphics ROM Bios as Vm option. Should i have to do this ? Do i need to delete the header as my graphic card is nvidia ?

I have followed the tutorial advanced gpu techniques from spaceinvadersone. I have modified my xml file, updated the bios from nvidia deleting the header. Same result the graphic card is not visible under windows on peripherals list….

 

😭😭😭😭😭

Any idea how to solve this problem ?

Here are my settings.

 

1/  I boot on  Legacy

2/ I have corrected the XML file config of the VM setting multifunction='on'  and correct values for the graphic card and sound as well.

 <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
      </source>
      <rom file='/mnt/disk1/isos/vbios/gpu_vbios.rom'/>
      <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0' multifunction='on'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x01' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x1'/>
    </hostdev>

 

3/ I have put video=efifb:off on syslinux

4/  The graphic card is connected with a HDMI to a screen

5/ I have not installed the NVIDIA drivers on Unraid as it is supposed to be used only on containers (but not VMs). But i think this has nothing to do with thiis.

6/ I have passed the VBIOS of the GC as parameter

 

=> The problem is still there no graphic card detected on Windows (see screenshoot).

Have you tried UEFI?

I was on UEFI and i didn’t succeed installating the VM at all, passing to Legacy allowed me to do so…

Edited October 21, 20223 yr by chis34

SimonF i tried again to boot in UEFI and same result 😩

I tried with or without  video=efifb:off and combinaison UEFI or Legacy same result…

Are you able to post a newer diagnostics? 

 

From the old one you have the nvidia drivers plugin which is not required if you passthru to a vm.

 

Are you using resizable BAR? maybe tried disabling in Bios?

Edited October 22, 20223 yr by SimonF

No the resisable BAR is disabled on the BIOS.

 

Here is a new diagnotics. Acfually i'm on UEFI with video=efifb:off on syslinux.

Have you tried creating a i440 machine type instead of Q35? 

 

With the current setup looks like you need a vbios, but others maybe able to help with that.

Edited October 22, 20223 yr by SimonF

No i didn’t i’m going to try it and let you Know…

I tried creating a VM Windows 11 with i440. I stay stuck on the VM with this screen. Tried to type reset but unable to validate the action ... 

Edited October 22, 20223 yr by chis34

Ok installation work in progress ...

Installed Windows 11 i mean the first steps before rebooting then when it reboots it get stucked on the TinaCore screen ... cannot go further ...

 

I stop / restart VM same result ... sound i440 does not work well

 

The end fo the VM log :

It works. Thank you so much to everyone for your help.

 

Some informations :

- i440 is working for me Q35 does not allow me to see the graphics card

- I had forgotten on the previous installation to install virtio-win-gt-x64 and  virtio-win-guest-tools => Do you think this could have made the difference between this installation and the previous one with Q35 ?

Glad its working for you.

As i' m stubborn i definitely gave Q35 a chance and it worked .... I don't understand why  ?? anyway both Q35 and I440 worked !!
