In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU. img,index=1 The FAT disk that I have attached as hda contains my GRUB and kernel image. Because of now using squashfs this is no longer possible; SquashFS is a filesystem and so must be mounted inside of the kernel, inside of the emulator. This is where QEMU (generic machine emulator and virtualizer) comes to play. The use of the QEMU package can help ease this burden. img', fmt=raw size=268435456 [[email protected] images]# Raw format with thick provisioning: (Provides Better Performance since it's pre-allocated storage).
