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.
Cheers,
Rusty.
