Hey all First experiment with VFIO. I'm running
Fedora 23 x64 with an Intel i7-6700k, and an R9 290. Host is booting with UEFI, guest is booting via UEFI. VT-D/VT-X/IOMMU are all enabled and seeming to function. The card works fine under Windows 10 (real hardware). Qemu's log and "dmesg | grep kvm" dont show any obvious errors. I'm using the builds from the virt-preview repo. My problem is.. The Win7 (and Win8.1) guests are perfectly fine and stable until I try to install the amd crimson drivers. Then Windows BSODs, yelling about an unhandled exception. If I unpack the install and install things piecemeal, then I can install the HDMI audio driver, and everything else okay...except for the display driver. Installing the display driver causes the BSOD. This happens on kernels 4.1 and 4.2. I'm using vfii-stub to stub out the hardware during boot on the host. I don't know what info would be helpful for debugging, just ask and I will supply as soon as I can. Has anyone had any success passing an r9 290? Cheers Eric
