debian-11.6.0-arm64-netinst.iso

Prerequisites

• AArch64 QEMU for x86_64 host
• QEMU UEFI image EDK2 BIOS
• Debian ISO for AArch64
• At least 2.5GB of storage for the VM

Create the VM

• Download Debian for AArch64 in ~/Downloads/debian-11.6.0-arm64-netinst.iso
• Create the guest disk

qemu-img create ~/VM/arm.img 2560M

• UEFI boot the Debian guest

qemu-system-aarch64 -machine virt -m 4096M -serial stdio -smp 4 -cpu max \
-bios "/usr/share/edk2/aarch64/QEMU_EFI.fd" \
-drive file=~/Downloads/debian-11.6.0-arm64-netinst.iso,\
id=cdrom,if=none,media=cdrom \
-device virtio-scsi-device \
-device scsi-cd,drive=cdrom \
-drive file=~/VM/arm.img,id=hd,if=none,media=disk \
-device virtio-scsi-device \
-device scsi-hd,drive=hd \
-netdev user,id=net0,hostfwd=tcp::5555-:22 \
-device virtio-net-device,netdev=net0

• Install Debian
• Retrieve the Kernel and Initrd images into the host

## Mount the guest disk
sudo modprobe nbd max_part=8
sudo qemu-nbd --connect=/dev/nbd0 ~/VM/arm.img
sudo fdisk -l /dev/nbd0
sudo mount -o ro /dev/nbd0p2 /mnt/
## Copy the images (not the symlinks)
mkdir ~/VM/arm/
cp -v /mnt/boot/vmlinuz ~/VM/arm/
cp -v /mnt/boot/initrd.img ~/VM/arm/
sync
## Unmount the guest disk
sudo qemu-nbd --disconnect /dev/nbd0
sudo modprobe -r nbd

Run the VM

qemu-system-aarch64 -machine virt -m 4096M -vga std -display none -serial mon:stdio -smp 8 -cpu cortex-a76 \
-initrd ~/VM/arm/initrd.img \
