siemens/4.19-rt vs. jailhouse/next. Should match. The bar_mask was copied over from the qemu demo. Other than that, the only thing that changed is the bdf. We simply chose a free one on our system. The memory region behin ivshmem is high memory above 32-bit. I instrumented and checked the code, but that shouldn't be a problem.
