Hi all,
I'm trying to implement PCI passtrough via virtualbox from Ubuntu 17.04.
I already ensured that I have iommu turned on, pci is put to stub, pci driver unbind, and pci is set to vfio-pci. However virtualbox still crashes at the start, and there are those strings in the kernel log
My question is what can be general_protection caused by in this case? Google says that it CPU error because of wrong memory addressing...
Any ideas or thoughts about it?
Thank you in advance, and sorry for a too general question ;)
