[Qemu-devel] [Bug 1680679] [NEW] qemu cannot run twice

[Qemu-devel] [Bug 1680679] [NEW] qemu cannot run twice

[Roger Lawhorn]

Public bug reported:

After using qemu with gpu passthrough and then shutting down windows 7 properly I cannot boot windows 7 a second time.
Only a full reboot of linux fixes this issue.
Qemu appears to corrupt something in linux when exiting.
I get no error messages but windows 7 never finishes booting during the 2nd try.
Apparently I do try to run vfiobind each time the script is run.
Wondering if rerunning vfiobind can cause an issue?

If you get one boot where GPU assignment works with a mobile GeForce,
you're doing better than most.

[Qemu-devel] [Bug 1680679] Re: qemu cannot run twice

[Roger Lawhorn]

NOTE: I only get gpu passthrough to work when using seabios. UEFI will
not work with modern nvidia drivers. You get the 'code 43' error because
whatever standards nvidia expects when talking to uefi are not met by
the OVMF firmware used by qemu. This issue happens to windows users
also. They had to update their uefi firmware to get around the code 43
issue.

Title:
  qemu cannot run twice

Status in QEMU:
  New

Bug description:
  After using qemu with gpu passthrough and then shutting down windows 7 properly I cannot boot windows 7 a second time.
  Only a full reboot of linux fixes this issue.
  Qemu appears to corrupt something in linux when exiting.
  I get no error messages but windows 7 never finishes booting during the 2nd try.
  Apparently I do try to run vfiobind each time the script is run.
  Wondering if rerunning vfiobind can cause an issue?

[Alex Williamson]

Comments #3 & #4 are not relevant to this bug and inaccurate
speculation.  There is no known incompatibility between NVIDIA drivers
and OVMF.  Many users, including myself, use this combination daily.
The issue is far more likely to be a VM configuration issue or lack of
UEFI support in the GPU ROM.

[Qemu-devel] [Bug 1680679] Re: qemu cannot run twice

[Alex Williamson]

Perhaps you get Code 43 because mobile NVIDIA chips make use of Optimus
which requires significant proprietary firmware support.  QEMU/VFIO has
never claimed to work with such devices.  The further speculation in the
original report that QEMU corrupted something in Linux seems
unjustified, the device simply doesn't work a second time.  This might
be lack of proper reset support in the GPU itself or poor interaction
with aforementioned proprietary firmware.

ok, so I will research qemu and nvidia optimus. I have a custom BIOS

  After using qemu with gpu passthrough and then shutting down windows 7 properly I cannot boot windows 7 a second time.

  Qemu appears to corrupt something in linux when exiting.
  I get no error messages but windows 7 never finishes booting during the 2nd try.

[Alex Williamson]

I suspect the 'M' in GTX880M is the biggest contributor to the Code 43.
The fact you can get it to work once per host boot on SeaBIOS is a
fluke.  If you can get custom ROMs, you might try playing with the vfio-
pci x-pci-device-id option to masquerade as a discrete card, maybe that
would avoid mobile code in the NVIDIA driver that would expect Optimus.
Obviously do so at your own risk.

It works using seabios. I assume that the nvidia driver cannot see
optimus, and expect an intel card also, unless I use OVMF. I do know
that you cannot run off the intel card in windows. It's a no-no. Thanks
for the bios tip. Maybe I can hide the optimus feature from OVMF and
windows.

I meant to say you cannot run without the intel card in windows if you
have optimus. I am glad seabios somehow hides optimus.

Does your Subsystem ID and Subsystem Vendor ID (of your GPU) show
correctly inside the WindowsVM?

It should be the same ID shown in your host. Otherwise that will trigger
the Code 43 error.

I once have this problem but now solve this by some vfio-pci option. Now
I have a laptop that passthrough my dGPU with OVMF working perfectly.

Thanks.
I will look into this.

Title:
  qemu cannot run twice

Status in QEMU:
  Invalid

Bug description:
  After using qemu with gpu passthrough and then shutting down windows 7 properly I cannot boot windows 7 a second time.
  Only a full reboot of linux fixes this issue.
  Qemu appears to corrupt something in linux when exiting.
  I get no error messages but windows 7 never finishes booting during the 2nd try.
  Apparently I do try to run vfiobind each time the script is run.
  Wondering if rerunning vfiobind can cause an issue?
