I'm not considering using QEMU because, even if I got it working, I will 
not be able to use it during my tests since I have a Perl program (that 
uses fork to divide processing work) that I would like to test if it can 
be improved without huge changes to it.

Unless using QEMU helps me identifying an error during the procedures 
I'm executing, I do not see many reasons to using it. The hardware that 
I have available for testing does not have multiple processors/cores so 
I could take advantage of them by using hardware emulation.

Please advise if QEMU could be used during my tests. I really don't know 
much about virtualization with QEMU.

Thanks in advance,
Alceu
