I support you on this, I brought this on the table last year too. We are 
not using serial console and this is a big issue for us too.

In our case we do CD-based anaconda installations that (on success) 
automatically reboot. Since we cannot eject these virtual ISO images they 
wait on the isolinux bootprompt after this reboot.

It may take a few days (in some cases were we do test installations weeks) 
before the machines are booted (or re-installed) and it is wasting CPU 
power.

On a physical machine it's less disturbing since it is dedicated hardware 
(still not OK for green computing) but in virtualization this is a huge 
problem.
