Ok, just as another hint: you should definitely take a look at pfault_interrupt() in arch/s390/mm/fault.c, which manages notifications about host memory manangement, so that the guest can put a task to sleep that accesses a page on the host block device, instead of suspending the entire guest, while waiting for the page to come back. arch/s390/mm/extmem.c has another very interesting concept, though the hcall interfaces used there are not as flexible as they should be in kvm. It's basically about mapping host files into the guest real address space, e.g. for shared memory between guests.
