<p dir="ltr">We still have i*-4xxx cpus in stock in my country.(hell, even socket 775 is still can be found) So it depends on where do you live.<br>
You will need VT-d. Or AMD-Vi.<br>
All the recomendations are available on the blog, plus a very verbose guide on how to glue it all together.</p>

I found it, but on the page it also says that "<span style="font-family:Arial,Helvetica,sans-serif"> I wouldn't
necessarily recommend this particular setup (it's probably only
available on ebay anymore anyway)". <br>
Any specific chipset I should aim for? I guess the CPU (i3, i5 or
i7) won't make a big difference as long as VTx is shown in the
datasheet? The google docs file shows many older models that are
not not sold anymore. Especially I would like to pick a
motherboard that has proper iommu separation of the primary
pcie-slot. So I don't need kernel patching.<br>

Sorry, I have other things to do within the next year ^^<br>

<div>OK, now this is a new information for me. I thought all
along that my problem is the graphics card.<br>
<br>
I tried to understand your whole message but I got lost at
MMIO and PIO.<br>
For the sake of saving my precious time and avoiding
frustration, I should better get a new motherboard and
CPU? How high are the chances it will work with my GXT750
Ti?<br>
Any hardware suggestions (I have DDR3-1600 memory that I
would like to keep using)?<br>
<br>
Thank you<br>

<p dir="ltr">You have an AMD FM2 CPU.<br>
Do use SeaBIOS and make use of VGA I/O lines, you must
have a VideoBIOS Extension support in your GPU's
firmware. Since we are in the 21'st century, you have
it.<br>
But the problem is that in order to make VGA work in a
VM we must translate MMIO, PIO and IRQs needed into the
VM.<br>
That is where IOMMU kicks in, and the related part of
software is vfio-pci's x-vga option. <br>
Usually you enable x-vga, vfio tells IOMMU to translate
all VGA related stuff from GPU to the VM and vice versa,
but on that particular platform(AMD FM2) something is
broken in hardware that crashes the IOMMU and the CPU
when trying to work with VGA.</p>

What do you mean you are suspicious of
pci-stub?<br>
All tutorials I've seen so far require you to
prevent nuveau from<br>
grabbing the card. Also in your very well
written tutorial I followed<br>
and helped me a lot.<br>

<br>
I just tried the MSI GTX 750 Ti with Bios mode
(bios selection switch -><br>
1, followed by host reboot). But it behaves
the same. I see the ovmf<br>
bios and boot splash, but then loss of signal.<br>

<div>It's not that you're using pci-stub, it's
that pci-stub is built as a module on your
kernel and you need to be sure to put all the
pieces in place to make sure that module gets
loaded before anything else that might touch
the device. As I said, it appears to be
working, but you're still getting a code 43. </div>
