[vfio-users] IGD primary pci passthrough troubles - can anyone help?

[Paul Handy]

Here's a full output of /proc/iomem after I try to boot a vm.
http://pastebin.com/WVhpzWSc

I'm not sure how to interpret it exactly, but below the first occurrence of
0000:00:02.0, there's BOOTFB. I don't know how more to disable early
framebuffers than I already have.

And for a more full log of the vm startup:

I'm not sure what the deal is, but windows definitely gets an opportunity
here to insert an error message.
