So, the past days I got time to try this qemu thing again, and now its working! :) Thanks matt_hargett . Is there also a way to access the webinterface of the nas? Entering the IP Adress of the qemu results into a 404 error. (running it on windows7 with enabled iis)

EDIT:

You have to start the service by your self. /etc/init.d/frontview start

and

passwd admin
Enter new UNIX password:

Hello,

I tried to run qemu under windows7 by using the image. But when I enter the command as in the video posted nothing happens. As you said, there will no error be displayed I have no idea what I did wrong.

I can do another one for recent versions of Linux/MacOS if need be, but this one is detailed enough that users of other platforms should be able to translate the steps.

I hope this helps, please leave feedback and thumbs it up. If anyone is in the giving mood after watching, please buy some of my band's songs @ http://themakingofthemakingof.com :)

You are not alone in that. Guys, suggest something if there is. Grateful!

Hmm... I'm running the images with the with "Q" ( the Mac qemu-Port ) and after starting apache and hitting HTTP the CPU usage spikes so bad that Chrome times out over an over again... I am trying to run Q on a MacBook Pro, but's I'm surprised it's this slow.

Also Frontview is empty?

Is this expected? Do I need to boot up some other services? Or is this image really just for building other stuff not emulating the full ReadyNAS?

-Thx

The QEMU image is not based on RAIDiator, so you can't upgrade the QEMU image to 4.1.7. It is just a Sparc emulated Debian Linux, that can be used to compile code to run on the ReadyNAS.

So, if I compile something on the QEMU virtual machine, is the resulting object binary compatible with the NV+ ?
ie Can I just copy and run, or do we have to recompile the source on the NV+ ?

What OS is actually running on the NV+ ?
