According to this forum thread:
http://www.amiga.org/forums/archive/index.php/t-33796.html
you may need to manually set boota-device to your boot device before 
trying to boot it.

But AFAIK this iso was an abandoned hack that is only supposed to sort of 
work on a specific Mac mini (1.5GHz G4 with 64MB Radeon Video) so not 
likely to do anything remotely usable on current QEMU so I would not spend 
too much time with it. Even on the mini it was made for it had no network, 
USB and other problems were mentioned in posts I've seen so I'd expect it 
to be problematic.

Also the MorphOS has some problems. It can be booted but it has no drivers 
for any QEMU emulated graphics (or vice versa) so you won't see anything 
even when it boots. Also versions above 3.7 has bugs that will prevent it 
from booting and even when it does boot it's very slow. I'll give that 
another try when new MorphOS and QEMU versions will be available to see if 
anything has improved.
