Configuring a VM for driver development

PreviousWindows

Last updated 4 months ago

The easiest way to build and test drivers is via a hypervisor that supports kernel debugging. I use my physical Windows host to write and build the driver, and another Windows host running virtually in Hyper-V to load and test it. Hyper-V allows the physical host to attach a debugger to the virtual host via a COM port to inspect memory etc, and crashing a VM is far less hassle than crashing your host.

Before being able to write a driver, head to the (WDK) page and follow the steps outlined on your host/dev machine: first set up Visual Studio 2022 and install the following packages from "Individual Components":

  • MSVC v143 - VS 2022 C++ ARM64/ARM64EC Spectre-mitigated libs (Latest)

  • MSVC v143 - VS 2022 C++ x64/x86 Spectre-mitigated libs (Latest)

  • C++ ATL for latest v143 build tools with Spectre Mitigations (ARM64/ARM64EC)

  • C++ ATL for latest v143 build tools with Spectre Mitigations (x86 & x64)

  • C++ MFC for latest v143 build tools with Spectre Mitigations (ARM64/ARM64EC)

  • C++ MFC for latest v143 build tools with Spectre Mitigations (x86 & x64)

Then install the Windows 11 SDK (Windows SDK 10.0.26100.1) from the C++ Desktop Development options; now install making sure to tick "Install Windows Driver Kit Visual Studio extension".

Now from a elevated CMD session run the following

bcdedit /debug on
bcdedit /dbgsettings serial debugport:1 baudrate:115200
bcdedit /set testsigning on

BCDEDIT is the Boot Configuration Data Store Editor which can modify the boot configuration for Windows: the first command enables kernel debugging and the second command configures the debug parameters. The debugport number should correspond to the COM port number we configured with the named pipe. he third command permits Windows to load test-signed drivers (which is disabled by default).

Next, open regedit (also in an elevated context) and navigate to HKLM\SYSTEM\CurrentControlSet\Control\Session Manager. Create a new Key called Debug Print Filter and within that, a new DWORD Value. Give it the name DEFAULT and a value of 8. This will allow Windows to generate kernel debug messages, which are disabled by default.

Now reboot the VM.
