<div dir="ltr">Hello everyone,<br>
<br>
I have been following the guides on the vfio blogspot for setting
up a Windows guest for gaming by passing it my NVIDIA GeForce GTX
980 graphics card. I have an AMD Radeon R7 250 graphics card for my
Linux host. I have ran into a strange problem and have not managed
to find a solution to it online, so I decided to come here and see
if anyone knows anything about it.<br>
<br>
Here is the problem I am facing:
<div><br></div>
<div>I installed the Windows guest (Windows 10 Pro) in a kvm
virtual machine made with virt-manager, using the default qxl/spice
setup during the installation, as instructed <a href="http://vfio.blogspot.bg/2015/05/vfio-gpu-how-to-series-part-4-our-first.html" target="_blank">here</a>. After the installation completed, I
removed any extra virtual devices and added the PCI host/vfio
device for my NVIDIA graphics card. I also edited the XML to hide
the kvm virtualization, in preparation for installing the NVIDIA
drivers on Windows, when I boot with my actual graphics card. I
have made no attempt to configure hugepages yet.</div>
<div><br></div>
<div>However, when starting up the VM, Windows no longer booted
successfully. I saw the Tianocore splash on my physical monitor,
followed by the Windows logo. The Windows logo stayed frozen
(without the spinning loading indicator under it) for a few
minutes, and then the spinning-dots loading indicator appeared for
a few seconds and the machine *reset*. It kept resetting again and
again, never getting past the Windows boot screen.<br>
<br>
I would assume that my PCI passthrough worked successfully, since
my physical monitor turned on and I saw the video output from the
virtual machine on it. However, I can't figure out why Windows
cannot finish booting successfully. Any help with this issue would
be greatly appreciated.
<div><br></div>
<div>The same copy of Windows (or rather, installed from the same
installation ISO) works fine with my NVIDIA card on my actual
hardware / when not in a virtual machine, so I am sure this is not
a hardware problem.<br>
<br>
<br>
Here is some relevant information about my system:
<div><br>
/proc/cmdline:<br>
... intel_iommu=on iommu=pt
vfio-pci.ids=10de:13c0,10de:0fbb,8086:8d26 vfio.disable_vga=1 ...
<div>(I omitted my rootfs and other irrelevant kernel
options)</div>
<div>The PCI IDs listed in my kernel commandline are my GPU, its
audio, and an EHCI controller on my system for USB, in that
order.</div>
<div><br></div>
<div>I did not need to use any "hacks" like the ACS override patch
or the enable_unsafe_interrupts option, since I did not experience
the relevant issues that they were made to fix. Each one of the PCI
IDs above is in its own IOMMU group. My system has no integrated
graphics (Core i7 Extreme 5960X CPU).</div>
<div><br></div>
<div><br></div>
<div>These lines appeared in dmesg when the VM started:</div>
