Using small requests may be a bit inefficient, but it still works and allows the guest to make progress. Allocating very large quantities of memory is very likely to kill the VM one way or another. This is not acceptable, especially when the guest hasn't even done anything wrong. There are legitimate circumstances where the size of the outstanding IO requests may be comparable to the guest ram size.
