No, it's virtio's bug. It makes sense to push workaround for guest bugs
as far from the hypervisor as possible.
If we want to increase the alignment in QEMU, I would prefer to have
natural alignment which makes some sense and happens to work around the
bug as well. Michael, Eduardo, any third opinions?
