[HELP] Emulating OpenWrt raspberry pi img on QEMU?

Hello All,

I'm a newbie to OpenWRT I've successfully build an image for raspberry pi B model and would like to emulate the image using QEMU but since the bin/target/ folder contains a (.img) file how do I emulate this using QEMU?

I've converted the (.img) file to (.qcow) file but unable to mount.

Pls, help.

Please read the QEMU wiki page.
I don't use qemu-system-arm, but it should even be possible to run a raw .img with it.
