Running images in QEMU

As many projects have a small portion that is hardware dependent, the hardware emulation comes to speed up the development process by enabling sample to run without involving an actual hardware.

Quick EMUlator (QEMU) is a free and open source software package that performs hardware virtualization. The QEMU-based machines allow test and development without real hardware. Currently, the ARM, MIPS, MIPS64, PowerPC, and x86 and x86-64 emulations are supported.

The runqemu script enables and makes the use of QEMU with the OpenEmbedded-Core supported machines easier. The way to run the script is as follows:

$: runqemu <machine> <zimage> <filesystems>

Here, <machine> is the machine/architecture to be used as qemuarm, qemumips, qemuppc, qemux86, or qemux86-64. Also, <zimage> is the path to a kernel (for example, zimage-qemuarm.bin). Finally,<filesystem> is the path to an ext3 image (for example, filesystem-qemuarm.ext3) or an NFS directory...
