qemu is 1.0 ???? Man, I need to to keep up.

aqemu is nice, switched to it from a myriad shell scripts when I started 
to forget which script did what and was writing a "generic" script to 
manage the VMs.  aqemu was easier for me to implement and keep track of 
the main options.

I use kvm-amd module in the stock kernel.  I don't see much difference 
on my Athlon64 X2 system and not much difference to Virtualbox 
(excepting graphics acceleration). Although the current SBo readme for 
qemu implies kqemu is needed, it is not as that functionality is already 
built in as I understand from the docs.
