Code 43 NVIDIA driver error within Windows 10 VM, Geforce 750 Ti Passthrough

boethius said:
I created a new VM to test, using no VIRTIO drivers...
Now when I boot, I get a black screen (the monitor has 1 dead pixel which flickers). I restarted after Windows automatically updated display drivers. I can only get to the desktop when booting in safe mode. I uninstalled the 750ti drivers in Safemode, disable automatic driver installation, reboot normally into desktop, and within 10second it crashes to the black screen.

Here is the cmdline from the new VM...
Code:

Really don't known here ... (same problem with ide drive vs sata ? with/without machine 2.2 ?)

can you install windows without pci-passthrough (hostpci0) ? then readd the device ?
 
On the second VM, I can boot with no hostpci entry, but when I add it I get the black screen.
 
I created a third VM, this time installing oldest nvidia drivers available that were not beta.

I got black screen during driver installation, and on subsequent reboots.
Edit: Rebooted once more, now at desktop with code 43 again...

Ok, I have found some news info here in the post comments:
http://vfio.blogspot.com.au/2014/08/vfiovga-faq.html

Seem that last nvidia drivers are very agressive with verifications,
if you can try drivers < 347.xx

For the latest drivers,
It seem that qemu 2.5 has a new feature
-cpu host,kvm=off,hv_time,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff,hv_vendor_id=Nvidia43FIX

can you try to edit:
/usr/share/perl5/PVE/QemuServer.pm

and change
Code: 
       if ($xvga && $xvga ne '') {
            $kvm_off = 1;
            $vga = 'none';
            $nohyperv = 1;
            if ($conf->{bios} && $conf->{bios} eq 'ovmf') {
                $xvga = "";
            }
        }

to
Code: 
       if ($xvga && $xvga ne '') {
            $kvm_off = 1;
            $vga = 'none';
             push @$cpuFlags , 'hv_vendor_id=Nvidia43FIX';
            if ($conf->{bios} && $conf->{bios} eq 'ovmf') {
                $xvga = "";
            }
        }

then restart

# /etc/init.d/pvedaemon restart

in your vmid.conf,
remove "machine: pc-2.2"

and start the vm again

(and send me the kvm command for verification)
 
I edited QemuServer.pm to include the change, does the deb file do anything else? To get to the desktop without the broken screen on the first VM, I have to remove hostpci0, use VNC to see Windows desktop, then uninstall the 750ti. as soon as I reboot with drive installed it gives the broken screen. The third VM crashes to a black screen either at boot or within 2-3min of being in windows environment. I installed windows on another HDD and booted to it directly on the same system, everything works fine and is stable. I am wondering if there is anything outside of proxmox that could be causing the problem? Extremely frustrating issue... Probably have spent 10+ hrs trying to get it to work. I'm hoping it is not a stupid mistake I have made (kinda new to linux/proxmox)...
 
Hey spirit. I'm been working on my rig. I'm now all caught up to this guy. I get windows to boot and install the drivers. PCI passthrough is working. BUt I get error 43 driver. Have you herd of the cpu option kvm=off? That seems to be the fix that i've seen most people use. But they are using qemu directly not through proxmox. I will try you fix above and report back some time tomarow as I need to get to sleep now before school starts in a few hours. Take care buddy and thanks for the help.

kvm=off is already send by proxmox.
(you can check the kvm command line)

can you try
http://download.proxmox.com/debian/dists/jessie/pvetest/binary-amd64/qemu-server_4.0-59_amd64.deb

I have apply all last fixes (hv_vendor, disable vnc).
After that,I'm out of ideas....
 
I installed that package and still getting the same issues.. I don't know what I could have done wrong or what is causing this to not work for me vs others... when I have some spare time I will go through everything and document all the steps I take. Strange that I experience either a black screen or a broken screen on the two different VM's
 
I get odd errors about hv-vendor-id property not found

before the last update (http://download.proxmox.com/debian/dists/jessie/pvetest/binary-amd64/qemu-server_4.0-59_amd64.deb) i had error43 in my win8-1 guest
 
Also, I have read about hv-vendor-id in fresh qemu versions, so in helps to fool nvidia driver (also hyper-v enlightments)
The only question is how to turn them on now.
 
Hey it's working!!!:):):):):):):):):):):):):):):):):):):):):):)

Win7
SeaBios.
All I did to clear the driver error was to add the expermintal repo and run dis-upgrade like you told me in the other thred. I had lost this upgrade because I had to wipe the host durring my fiddling to fix all this.

Note.
I did not have to inistall the deb or edit the script. Just ran the update.


:confused:Now all I have to figure out is why my keyboad is fussy about USB passthrough.

It will work the first boot but if i reboot the guest it will fail to reconnect and stubbornly stay connected to the host. Untill I shut off the whole machine. Mouse works fine on guest reboot.

Hey Spirit can you please pm me your email. I would like to paypal you some money to buy you a coffee for all your great help :) Sorry I cant offer more I'm a poor student.

EDIT: if anyone has the same usb issue i have. shutting down the guest(instead of restarting it) seems to allow the keyboaed to work again.

YESSS !

can you send your
- vmid.conf
- #pveversion -v
- maybe other tuning done in grub

I'll update the wiki

my email can be public : aderumier@odiso.com ;)

No need to paypal, I'm glad to help the proxmox community.
And thank you to have take time to test, because my geforce 970 is not able to passthrough currently, so I'm blind for testing currently ;)
