qemu-kvm: Add sda alias options to hda options
I know that the name hda come from IDE drive, but I felt strange
when I use qemu to boot linux kernel directly as follows:
$ qemu-system-x86 -kernel vmlinux-2.6.28.15 -initrd
initrd.img-2.6.28.15 -hda vdisk.img
By applying this patch, the command will change to:
$ qemu-system-x86 -kernel vmlinux-2.6.28.15 -initrd
initrd.img-2.6.28.15 -sda vdisk.img
The latter one seems to be more intuitive for me.
