There is something wrong with the test suite that it isn't covering
the above, I'm going to look into that today.

sounds to be the cause. I didn't see any significant change in vfio_main.c
that may fail gvt. So should the iommufd changes. Then we will re-run the
test after your update.:-)

I updated the github with all the changes made so far, it is worth
trying again!

gvt is still failing with below call trace in host side. vfio_unpin_pages()
is still in problem. Any idea on it?
