Hi,
I have a problem getting gpu passthrough working. My hardware: CPU: Xeon E5 2695 v2, GPU to pass R9 390, host GPU GTX 550Ti, mainboard: ASUS Z9PA-D8.
vfio-pci seems to work:
also the iommu groups looks good:
I also made a non shadowed copy of the rom because the R9 390 is my primary GPU.
but when I start the vm I get:
and after bootloader when it tries to load windows I continuous getting:
I hope someone can give me a hint ;)
some additional info:
qemu args:
