This repository contains necessarities to build a VM image and corresponding hypervisor image using Dockerfiles.

Edit corresponding files in image/overlay to customize VM behaviour. Privileges are required for building VM images as some scripts are depending on /dev/nbd.

Build & Running

# cp .env.example .env
# vim .env
# VM_OPTS="--no-cache" HY_OPTS="--no-cache" make
# fallocate -l 128G ./data/data.raw
# sgdisk -o -n 1:0:0 -t 1:8300 ./data/data.raw
# losetup -Pf ./data/data.raw
# mkfs.ext4 /dev/loop0p1
# losetup -d /dev/loop0

# vim docker-compose.yml
# docker compose up

The given compose file is for reference only. It must be edited according to your situation.

Once the image is built and udhcpd is ready, VM's IP will be shown in logs.

By default, a OpenSSH server will be listening on :2222.
