It starts fine after guest reboot and guest poweroff, but when I install the AMD Crimson driver in the guest, the VM is only booting the first time after host boot. The second time I start the VM my monitor stays black/off no matter what I boot (with or without driver).<br><br>I have a MSI Z77G45 with an Intel i7-2600 and a AMD R9 285. I use the IGD for the host and the AMD card for the guest.<br>As host I use Arch Linux and as Guest Windows 8.1. I blacklisted amdgpu and radeon, I load vfio-pci with options vfio-pci ids=1002:6939,1002:aad8. I tried it with 4.3.3-2-ARCH and 4.1.15-1-ARCH kernels, but both have the same behavior.<br><br>I installed Windows 8.1 in UEFI/OVMF mode.
