Your first Ubuntu image¶

This tutorial will walk you through creating your first Ubuntu image and launching it in a virtual machine.

Install dependencies¶

sudo apt-get update
sudo apt-get install git snapd qemu-user-static ubuntu-dev-tools
sudo systemctl restart systemd-binfmt
sudo snap install --classic ubuntu-image

Clone the gadget repository¶

git clone https://github.com/canonical/risc-v-gadget.git

Build the image¶

cd risc-v-gadget
sudo ubuntu-image --workdir workdir --debug classic image-definition.yaml

Test the image¶

For running the image in a virtual machine install the runtime dependencies.

sudo apt-get install opensbi qemu-system-riscv64 u-boot-qemu

Navigate to the image and change the owner.

cd workdir
sudo chown $USER ubuntu-*-preinstalled-server-riscv64.img

Launch the virtual machine.

qemu-system-riscv64 \
  -machine virt -nographic -m 2048 -smp 4 \
  -bios /usr/lib/riscv64-linux-gnu/opensbi/generic/fw_jump.bin \
  -kernel /usr/lib/u-boot/qemu-riscv64_smode/uboot.elf \
  -device virtio-net-device,netdev=eth0 -netdev user,id=eth0 \
  -device virtio-rng-pci \
  -drive file=ubuntu-*-preinstalled-server-riscv64.img,format=raw,if=virtio

You will be asked to change the password.

Power off the virtual machine with

sudo poweroff
