I didn't look at them until now, but yes, at 5 MB vs 56 MB this makes
sense.

*This* was what i was looking for. I couldn't really find anything
published about the differences between the two different releases in
any prominent place.

if qemu-kvm ist more advanced in the kvm regard and can offer the same
functionality with an added --target-list, wouldn't it at least make
sense to build both packages from the qemu-kvm sources? (I thought
until now, the kvm sources wouldn't support other targets than
x86(_64).)

As far as I understand, at the moment I have to choose between either
latest and greatest kvm performance *or* multiple target support.

+1 :)

P.S.: As a sidenote: Is it normal/intentional that I don't get my own
mails back via the list? Or is this some weird GMail stuff?
