Note

Note: please keep in mind that hypervisors change over time because new features are added to the operating systems or using new technologies. For example, updates to Meltdown & Spectre have made a lot of changes to the hypervisors, so if you want to use Hypervisor From Scratch in your projects, research, or whatever, you have to use the driver from the latest parts of these tutorial series as this tutorial is actively updated and changes are applied to the newer parts (earlier parts keep untouched) so you might encounter errors and instability problems in the earlier parts thus make sure to use the latest parts in real-world projects.

Compile & Install

In order to compile this project, you have to use Windows Driver Kit (WDK), first install Visual Studio, then install WDK. After that, you can compile it.

Environment

All the drivers are tested on both physical-machine, and VMWare Workstations's nested-virtualization, from part 8 support to Hyper-V is added, which means that you can test part 8 and newer parts on physical-machine, VMWare Workstation's nested-virtualization, and Hyper-V's nested-virtualization.
