Once the SSH connection has been established, VisualKernel will ask you for the build settings for your module:.VisualKernel will begin waiting for the VM to start the SSH server: If the SSH server doesn’t start automatically, follow the instructions on this page to install and start it manually. Enter the settings and press “Connect”.VisualKernel will ask how to connect to the VM using SSH: Once the Linux OS has been installed, click “Next” in the kernel module wizard.When the installation is finished, proceed with rebooting the VM: This should unfreeze the VM and allow you to install the Linux OS as usual:.run file in the VM directory and find out the GDB port used by the VM: This happens due to the way QEMU emulates timer interrupts in real mode (before Linux is loaded) and does not affect other functionality: Fedora/CentoOS, but not Ubuntu) may freeze on the initial countdown screen. Depending on the QEMU version you are using, some Linux installers (e.g.VisualKernel will save the settings you entered and will start the VM automatically.

When VisualKernel asks for the VM parameters, enter the VM name/location and point it to the installer disc image: Press “OK” to create the VM. Once QEMU has been installed, click “Create a new virtual machine”.You can read more about VisualKernel integration with QEMU on this page. If you have not installed QEMU before, click the “Install QEMU” button to automatically download a Windows build of QEMU: Note that unlike VMWare or VirtualBox, QEMU does not need to install any services or drivers on the Windows machine and can be installed without using an administrator account. Select “ Setup a new target for running Linux kernels -> Use an existing virtual machine -> QEMU“. The easiest way to get working would be to download an existing pre-built VM image, however in this tutorial we will show how to create a QEMU VM from scratch.

The next page of the wizard allows selecting the kernel target.

In this tutorial we will use the basic “Hello, World” template, however you can choose any other template you prefer:

Choose the project template you would like to use to create your first kernel module.

Enter the name and location of the project you would like to create:.

Start Visual Studio and locate the Linux Kernel Module Wizard:.

QEMU is very lightweight, requires no initial setup and is the only virtual machine engine that supports kernel debugging on Windows hosts running the Hyper-V platform (required for WSL2).īefore you begin, install Visual Studio and VisualKernel 4.0 or later. This tutorial shows how to use VisualKernel and QEMU to efficiently develop and debug kernel modules.
