Actually, the block code should be able to deal with unaligned buffers since qemu rev. 4599. This change seems to be present in current KVM. Can you tell exactly which operation failed? But apart from that, qemu_memalign is the right thing to do, because copying from/into an aligned buffer in the block code costs performance (don't know how much, though).
