I'm trying to install modern Radeon drivers on the guest. I'm currently trying 19.4.2, but have tried back through mid-2018 drivers. Install progresses to 33%, hangs, and then BSODs with a PAGE_FAULT_IN_NONPAGED_AREA. Drivers from Windows Update work fine, but are pretty old and seem to be lacking Vulkan support (188.8.131.52, dated 4/24/17). Event viewer says:
The computer has rebooted from a bugcheck. The bugcheck was: 0x00000050 (0xfffff8020000000e, 0x0000000000000010, 0xfffff8020000000e, 0x0000000000000002). A dump was saved in: C:\WINDOWS\MEMORY.DMP. Report Id: aac0ab2d-f025-4f16-9e15-079560d86e43.
Here's the backtrace from the above dump, so pdbs so no function names for the driver:

Hardware: Intel i7-2600, Gigabyte Z68MA-D2H-B3, Radeon R9 280X

I have the following module option set:
options kvm ignore_msrs=1 options vfio-pci ids=1002:6798,1787:3001,1002:aaa0,1787:aaa0 disable_vga=1
I also have dracut configured to load early so that the radeon/amdgpu drivers do not get loaded before vfio-pci. I confirmed this with lspci output. intel_iommu is enabled in the kernel arguments, no scary errors in dmesg.
Things I've tried:
- disable_vga argument on vfio-pci
- adding video ROM
- i440fx chipset with SeaBIOS (totally different VM)
- connecting GPU via ioh3420
- updating virtio drivers (originally on 0.1.141)
- Remove QXL adapter
- Move to a dual core, single thread CPU
- DDU between each attempt
However all of these result in the same exact behavior.
Any pointers or success stories would be appreciated. I'm happy to give any other information needed.

Possible one of the steps in the above links might solve your problem.
I went to AMD Download page and all the different type of Linux drivers are all from 2015:AMD Radeon™ R9 280X Drivers & Support | AMD
Not sure which one is compatible with Fedora 29.
Found this Fedora Website that has AMD Driver for Fedora 29: xorg-x11-drv-amdgpu-18.1.0-1.fc29.x86_64.rpm Fedora 29 Download
See if this AMD download helps. Cant verify whether it is a safe download or not, but none of my Web security add-on indicates it is an Unsafe website.
The key was hiding KVM and setting a bogus hypervisor id.
This is strongly reminiscent of NVidia's attempts of preventing passthough, although they are nice enough just to refuse to load the driver and log a vague error code instead of putting the guest into a boot loop. This is a major reason I don't buy NVidia hardware.
AMD: What the hell?
