Probably makes sense to make this the default.

It is difficult to anticipate future uses of any piece of software. I
can think of a few cases where I would want to set this behavior on a
case-by-case basis, for example, running an OS that was installed on
real hardware originally. Therefore, if it were to come down to a vote,
I would say it should be a command line option. The patch submitted
earlier illustrates how trivial it would be to make it configurable at
runtime.
As for a cluttered command line.. yes, I agree it is getting cluttered.
In addition, the current syntax will eventually limit future emmulated
hardware (scsi bus, more than 4 IDE disks, etc). Is there any effort
currently in the works to move the command line options into a config
file for more versatile runtime configuration? When I find time, I
might work on this, if no one else has started it...
