In particular, you can use this to set driver properties for devices which are
created automatically by the machine model. To create a device which is not
created automatically and set properties on it, use -@option{device}.
The two syntaxes are equivalent. The longer one works for drivers whose name
contains a dot.

then the virtual cpu speed will be automatically adjusted to keep virtual
time within a few seconds of real time.
When the virtual cpu is sleeping, the virtual time will advance at default
speed unless @option{sleep=no} is specified.
With @option{sleep=no}, the virtual time will jump to the next timer deadline
instantly whenever the virtual cpu goes to sleep mode and will not advance
if no timer is enabled. This behavior give deterministic execution times from
the guest point of view.
Note that while this option can give deterministic behavior, it does not
provide cycle accurate emulation. Modern CPUs contain superscalar out of
order cores with complex cache hierarchies. The number of instructions
