How to attach a disk image to QEMU containing root?

You created the filesystem on the entire volume (file), not on a partition. If you want it on a partition, then you would have to write a partition table in the file and create the filesystem in the partition. Edit. Not sure if grub even has a way to boot with no GPT or MBR.

Can you run QEMU on a Raspberry Pi?

I downloaded 2015-09-24-raspbian-jessie.img from the good folks at Raspberry Pi. When I try to run qemu-system-arm I get a kernel panic.

Why does QEMU not boot from the correct device?

The most likely thing is that the kernel doesn’t know the correct device to boot from. You can supply this explicitly from the qemu command line. So if the root is on partition 2, you can say: qemu -kernel /path/to/bzImage \\ -append root=/dev/sda2 \\ -hda /path/to/hda.img \\ . . . Notice I use /dev/sda2 even though the disk is IDE.

Why is my Linux image file not mounted?

Disable NMI watchdog on HOST for using performance counters on GUEST. You may ignore this. Hope this helps if someone has the same issues. maybe your system image file is bad and can not be mounted. You may try these command to mount the image file and check if it is a valid root file system for linux.

What kind of image format does QEMU use?

Old QEMU image format with support for backing files, compact image files, encryption and compression. If this is set to aes, the image is encrypted with 128-bit AES-CBC. The encryption key is given by the encrypt.key-secret parameter.

Do you need patches to use QEMU coreboot?

Qemu used to require patches to work with coreboot, but any current standard build (as packaged by distributions) should be good enough. If you are using FILO, you must create a hard disk image containing the Linux kernel and optional initramfs that FILO loads.

Can you launch the Linux kernel on QEMU?

I am able to launch the linux kernel on QEMU using -kernel and that’s pretty straight-forward and simple. But now I am attempting something different. I am simulating the combination of UEFI + GRUB + Kernel.
