Unless it has changed, it's not 1024 bits, but it's 1MB. According to my
notes, I was getting this error message otherwise:
"The size must be a whole number (in MBs)."

You can create an image file understood by qemu (and other tools) in
order to install grub & co. Then, use something like that:
qemu-img resize $image $roundedsize
qemu-img convert -o subformat=fixed -O vpc $image $vhd

it can be improved but at least it was working last time I used it ]
