So I'm guessing that this library is not publicly available right now?

Is this backend meant for integration into QEMU or does it run as
separate process?

How/Where could I integrate a passthrough backend like the one in this
patch series?


The polling code isn't really necessary for the host backend, I left it
there just in case it would be needed by such a socket interface as is
used in the Xen fork.

Of course.
