[Qemu-devel] define desired speed?

Any way to startup qemu with my own desired speed?

It does not have to be precise. And I don't want to slow down the host 
system itself.

For example, I am using a 1900MHz system and need to test some 
applications usability and performance as if it were running on a 233 MHz 
CPU (or close).

Bochs provides a CPU "IPS" (emulated Instructions Per Second) 
configuration that can be adjusted to get at least close to the desired 

I am using qemu-0.9.0 (on NetBSD), but I also looked at the online docs 
and didn't see anything related.

Also what do you use for benchmarking the estimated speed of qemu?

I know that BogoMips is not a real benchmark, but the Linux system I am 
running in qemu says it is at 7497.31 BogoMIPS which is the probably same 
as if I booted the Linux system outside of qemu on same 1900Mhz hardware. 
(I was hoping to see the BogoMips in the 200 to 700 range.)

p.s. I emailed your devel list because I didn't see a users list.
