May 28, 2017 · Boot system in QEmu. Note that for ARM we don’t need to specify RAM size, and nor do we need to force use of a particular console as the default: /usr/bin/qemu-system-arm -M versatilepb -kernel toolchain/etc/plx49/zImage-4.2.8 -initrd fs.squashfs -append 'root=/dev/ram0 init=/bin/sh'.

The syntax is: qemu-system-x86_64 -kernel bzImage -hda rootdisk.img -append "root=/dev/hda". Use -kernel to provide the Linux kernel image and -append to give the kernel command line arguments. The -initrd option can be used to provide an INITRD image.

28.02.2018 · For QEMU in system mode, we need to provide the emulator with a file system image and a kernel or BIOS image to use in the boot process. The file system image is easy to get since we extracted the squashfs root previously with binwalk, and it is relatively easy to create an image from this that QEMU can use. The kernel is trickier.
