[Qemu-devel] Simple, bootable benchmark floppy image

[Leonardo E. Reiter]

Hello,

we just created a simple bootable 1.44MB floppy image that runs nbench 
(Linux version of the old BYTEmark CPU/FPU/memory benchmark) inside a 
QEMU session.  The nice thing is that the image boots a Linux kernel and 
runs nbench automatically, then "powers off" with APM causing QEMU to 
exit.  Also, it is designed to be run with -nographic since it pipes all 
output to the serial port.  This gives us a convenient way to quickly 
run standardized benchmarks and capture the output on the host.

We have made this image freely available to everyone.  It can be 
downloaded from here:

	ftp://ftp.win4lin.com/pub/testing/nbench-qemu/

The README file contains all the relevant info, and all 
source/modifications used are available in the same directory.

This is very useful for us, and we hope someone else will find this 
useful as well.  If anyone wants to link to this FTP directory from a 
forum for example, please feel free to do so.  We can be (and have been) 
Slashdotted before for example, without server problems, so don't worry 
about distributing the link widely.

Note that this only runs on i386-softmmu targets, with or without KQEMU 
enabled.  Anyone who needs to can theoretically port this other targets.

Enjoy,

Leo Reiter

As an additional note, we realize this could have been probably been 
done with just the linux-user mode.  However for us it was important to 
benchmark a full softmmu session, since that is what we are using for 
our products.
