QEMU/KVM Minimal Debian Image Setup

This repository provides scripts for creating a minimal Debian image, running a Linux kernel using QEMU/KVM, and accessing the VM via SSH. The setup allows you to easily test and develop with a custom Linux kernel in a lightweight virtualized environment.

Contents

create-image.sh: Script to build a minimal Debian image.
run.sh: Script to start a QEMU/KVM instance running the Linux kernel.
enter.sh: Script to log into the QEMU VM via SSH.

Prerequisites

Before you begin, ensure you have the following installed on your system:

QEMU
KVM (Kernel-based Virtual Machine)
Debian (for the base image)
ssh client for accessing the VM

Usage

Step 1: Create the Minimal Debian Image

The create-image.sh script builds a minimal Debian image. To run this script, execute the following command in your terminal:

./create-image.sh

This script will create a root filesystem that can be used by the QEMU/KVM instance.

Step 2: Run the QEMU/KVM Instance

Once you have the minimal image created, you can start the QEMU/KVM instance using the provided run.sh script. Make sure to have your Linux kernel image (bzImage) available in the same folder. You can run the script as follows:

./run.sh

This command will launch the QEMU instance with the following configurations:

The created Debian root filesystem will be used as the root for the VM.
The networking model is set to 'user', which avoids any complex configuration on the host machine.

Step 3: Accessing the QEMU VM

To log into the QEMU VM, use the enter.sh script which sets up port forwarding for SSH. Run the following command:

./enter.sh

This script configures your SSH client to connect to the VM via localhost on port 10022. You can access the VM by executing:

ssh -i <certificate>  -p 10022 root@localhost

Note that 'certificate' is created during the image creation and is available in the root folder.

Notes

Ensure that the QEMU/KVM process has sufficient permissions to run and access the required resources.
If you encounter any issues, check the logs generated by QEMU for debugging.
Modify the scripts as needed to fit your specific use case or environment.
