Hm. I'm still a little confused. Does this mean you have something like

virtio shared memory region (with shmid) >= ism shared memory region >=
ism shared memory chunk

Than is multiple ism shared memory regions may live within a single
virtio shared memory region, and multiple ism shared memory chunks may
compose an ism shared memory region?
