[vfio-users] vfio_pci_read_config failed: Bad a ddress



Hello,

For the last week I've been trying to get GPU passthrough to work. My goal is to have a simple MSI Geforce 210 as the host graphics adapter, and pass a MSI GTX 970 GAMING to a Windows 8 guest. However, I can't get it to work. The 970 does give output when the drivers are not installed, but after installing the drivers qemu gives me the following error when Windows boots (the vm restarts after that and Windows goes into automatic recovery):

I'm currently running Fedora 23. I've tried kernels 4.0.4 (on fedora 22), 4.2.5 (both 22 and 23) and the 4.3.0 mainline version. I've tried both the i440fx and q35 chipsets. In the config file above I've tried to move the graphics card to an PCIe slot, but this didn't work either. It always ends in the errors above.

The weird thing is that while everything crashes with my 970, using a spare radeon HD 5870 instead of the 970 worked just fine after adding ignore_msrs=1.

Currently I'm at a total loss. Does anyone have an idea if this is even possible?
