Hey guys!

This is an awesome version of QEMU and I can use Virgil 3D (vGPU within QEMU Guests works ok) with the native Linux `radeon` driver.

However, if I try to install the AMDGPU-19.03 drivers, it completely breaks QEMU!

AMDGPU-19.30:

It breaks QEMU on Ubuntu 18.04.2 + Stein UCA Repo!!!

I also tried the previous AMDGPU versions, same results.

Here is the error after installing amdgpu:

How to repeat:

Here is what I do:

1- Install Ubuntu 18.04.2 (with HWE for Kernel and XOrg);
2- Enable UCA with `sudo add-apt-repository cloud-archive:stein`;
3- Install `qemu-vkm`, `virt-manager`, and etc;
4- You'll be able to create a QEMU Guest using Virgil 3D using the Linux `radeon` module! It's awesome.
5- Install AMDGPU-19.30 (or any other previous version), for an even more awesome QEMU? Let's see!
6- No deal, after installing AMDGPU drivers, no more QEMU!

Any idea about how to fix this? Is this an amdgpu limitation? Any idea if QMEU with Virgil 3D with it someday (or this isn't in the master plan)?

Cheers!
