so the question would be if QEMU has any mechanism to setup that
shared memory, right?

if so, how would that look to the guest OS?

i guess it would be nice if the "-net user" facility could emulate an
RDMA-capable card using real shared memory, but AFAIK, RDMA doesn't
look exactly like remote shared memory.
