right now kqemu needs an extra argument.

But very soon kvm will need it too. Like for example controlling knobs
like kvm-irqchip and kvm-pit. So maybe we want a standard way of passing
arguments for all accels?

How about --accel foo,args=bar,bar,bar with the args part being optional ?

An exampel would be --accel kvm,args=userpit,userirqchip (assuming we want the
default to be in the kernel)

Otherwise we're stuck with an evergrowing combination to support
