NoirVisor - Hardware-Accelerated Hypervisor solution with support to complex functions and purposes and nested virtualization.
NoirVisor is a hardware-accelerated hypervisor (a.k.a VMM, Virtual Machine Monitor) with support to complex functions and purposes. It is designed to support processors based on x86 architecture with hardware-accelerated virtualization feature. For example, Intel processors supporting Intel VT-x or AMD processors supporting AMD-V meet the requirement. By designation, NoirVisor determines the processor manufacturer and selects the function core.
Intel Processors based on Intel 64 and IA-32 Architecture, with support to Intel VT-x. Intel EPT is prefered, but not required.
AMD Processors based on AMD64 Architecture, with support to AMD-V. Nested Paging is prefered, but not required.
Other processors based on x86 architecture may be supported in future.
NoirVisor is developed in highest focus on nested virtualization. It is not currently supported, but will be developed in future.
Algorithm regarding the Nested Virtualization was stated down in the readme files in VT-Core directory.
NoirVisor is coded in the C programming language and the assembly since it is procedure-oriented designed.

DO NOT PROVIDE CODES WITH C++ WHICH INVOLVES THE NoirVisor Core IN YOUR PULL-REQUEST!
To build a kernel-mode driver on Windows, you should install Windows Driver Kit 7.1.0 to default path on C disk. Then run the provided batch file to build it.
Also note that, you have to create certain directories required by the batch complilation.
You may download the WDK 7.1.0 from Microsoft: https://www.microsoft.com/en-us/download/details.aspx?id=11800
Note that you should execute the build_prep.bat to make directories for first-time compilation.
There is a .NET Framework 4.0 based GUI loader available on GitHub now: https://github.com/Zero-Tang/NoirVisorLoader
If you are using operating systems older than Windows 8, you are supposed to manually install .NET Framework 4.0 or higher.
If you use the digital signature provided in NoirVisor's repository, then you should enable the test-signing on your machine.
NoirVisor is designed to be cross-platform. It can be built to a kernel-mode component of an operating system, or even as a software with bootstrap running on bare-metal.
Currently, NoirVisor supports the Windows Operating System newer than or same as Windows XP, running as a kernel-mode driver.
If there is already a hypervisor running in the system, make sure it supports native virtualization nesting.
Project NoirVisor has finished developping the basic hypervisor on Intel VT-x.
Now NoirVisor has three future development plans:
Remaster CPUID-caching architecture with a flexible design.
Develop Nested Paging with Stealth Hook on SVM-Engine for NoirVisor.
Develop Nested Virtualization.
Develop Hypervisor-Platform compatible hypervisor for Windows 10 Redstone.
- Stealth SSDT Hook (NtOpenProcess Hook) on 64-bit Windows, both Intel and AMD Processor.
- Stealth Inline Hook (NtSetInformationFile Hook) on 64-bit Windows, Intel Processor.
- CPUID caching architecture. (First Design)
- Critical Hypervisor Protection on Intel VT-x by Intel EPT.
- Software-Level Code Integrity Enforcement.
