[vfio-users] "BUG: unable to handle kernel NULL pointer dereference at 00000000000000a8"

I'm running Arch and updating recently has caused my VM to stop booting. Watching journalctl I see this when I try to start the VM: "Feb 23 15:04:07 haze kernel: BUG: unable to handle kernel NULL pointer dereference at 00a8 Feb 23 15:04:07 haze kernel: IP: down_write+0x12/0x30 and

Re: [vfio-users] Dual monitor with spice display + hdmi

That's an interesting scenario ... How does Windows handle multiple graphics cards? Like, let's say this was all bare metal, and the machine had 2 different models of nVidia cards and an ATI card, with a monitor connected to each card. Would Windows be able to display a desktop on each monitor, or

Re: [vfio-users] Mouse and keyboard for gaming

It's also worth mentioning that some gaming device software (I have personal experience with Logitech) doesn't work when the mouse is passed through via Synergy. I also had a condition, when passing the mouse through as a USB device, where the guest (Windows 10) wanted to update firmware on the

Re: [vfio-users] Mouse and keyboard for gaming

I have had awful experiences with Synergy and FPS games. I use Synergy for non-gaming times, and when the mouse doesn't need to be super awesome (like Civ, or Xcom). When I need all of the features of the mouse, I will pass it through via a dedicated PCI-USB card (the PCI card is passed through

Re: [vfio-users] Nvidia code 43 with Ubuntu 16.04 host

Simon, are you able to boot your VM with GPU passthrough and no Code 43 errors without enabling any hyperv features? Do this first, then move on to enabling Hyper V. "I cannot place the vendor_id flag in the xml because it is validated in the Ubuntu package" -- what does this mean? Is there

Re: [vfio-users] passthrough VGA for widespread use?

a) I've never had Host or Guest crash problems. I have had problems with programs crashing in the guest with nebulous errors (or no errors) that seem related to graphics. They are reproducible, but not reliably so, and I have never tried to verify if those crashes exist on baremetal. d) Synergy

No soup. Windows is only seeing 2-cores: http://imgur.com/tnOXfnx; perhaps this is the problem, Windows sees 2, GeForce Exp expects/sees 4? On Mon, Jan 25, 2016 at 8:46 PM, Alex Williamson < alex.l.william...@gmail.com> wrote: > On Mon, Jan 25, 2016 at 8:42 PM, Will Marler <w...

Re: [vfio-users] help with choice of GPU for passthrough

Not sure how anyone can possibly know the answer to your question about whether a bug will be fixed and when, or whether a super-new & very expensive card with hardly any testing time or exposure would work, but I suppose it doesn't hurt to ask. Perhaps your best course of action is to buy from a

Re: [vfio-users] Cannot have sound from the guest

I'm of no help wrt getting PulseAudio working. However, how important is this to you? A much better solution for me (I use the VM exclusively for gaming) was to get a $10 PCI USB card, and some USB headphones. I pass the PCI USB card through to the guest, and everything works better this way.

Are you going from Windows 7 to Windows 10? If so, then yes, I had the same problem. I couldn't solve it. I was only doing it to get a licensed & activated version of Windows 10; I had a Windows 7 key. If that's your situation, simply use the Windows 7 key you have with a fresh installation of
