It's entirely independent.  The domain says "send/receive the following
address,length pairs to/from this peer".  Now, if the hypervisor is
going to page-swap, then they're going to need to be page-aligned for
both, but the hypervisor is certainly not required to flip pages.  My
current implementation simply does a memcpy.
