This guide will walk you through installing QEMU in Termux, setting up an Ubuntu virtual machine, and even accessing a graphical desktop (LXDE) via VNC.
Introduction Termux is a powerful terminal emulator for Android that provides a Linux environment without rooting your device. But what if you need a full desktop Linux distribution? Enter QEMU – a hardware emulator that lets you run complete operating systems like Ubuntu right inside Termux.
Now create a meta-data file (can be empty):
wget https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-arm64.img For x86_64 devices (older/Intel-based Android):
touch meta-data Generate the cloud-init disk image:
cat > user-data << EOF #cloud-config users: - name: termuxuser sudo: ALL=(ALL) NOPASSWD:ALL shell: /bin/bash lock_passwd: false passwd: $(openssl passwd -6 'ubuntu123') ssh_pwauth: true packages: - vim - net-tools EOF This creates a user termuxuser with password ubuntu123 . You can change the password inside the single quotes.
ssh termuxuser@localhost -p 2222 Password: ubuntu123 (or whatever you set)
