Not sure what I was smoking when rewriting this 3 times: "VFIO is (except devices without a physical IOMMU or some mediated devices) incompatible with discarding of RAM. The kernel will pin basically all VM memory. Let's convert to ram_block_discard_set_broken(), which can now fail, in contrast to qemu_balloon_inhibit()." -- Thanks, David / dhildenb
