Testing with QEMU

QEMU is great for testing images and apps. There is no need to flash or install images back and forth on real hardware. Here are a few things that may help you testing OE stuff with QEMU.

Do's and Dont's

• use at least version 0.9x of qemu, earlier versions are unreliable
• if possible use the poky-qemu and poky-scripts, they are more widely tested than stock qemu
