[CentOS] kvm module and boot order

I use kvm-amd a lot to do test installs.
I am using it with qemu-kvm-0.14 the lastest.
I think your supposed to be able to give your command line
and add the parameter "  -boot  dc" so it initially boots with the cdrom (d)
and then after reboot will boot do the HD or c. This never works for me.
It always boots CDROM.

Is anyone using this argument. Is there something special to do in order
to get the first boot on CDrom then the next boot going to HD?

Thanks,

Jerry
