ExHyperV
ExHyperV is a suite of administrative tools designed for managing advanced Hyper-V configurations, specifically focusing on GPU partitioning, device passthrough, and virtual network switches. It provides a graphical interface to configure virtual machine resources and optimize hypervisor settings.
The project is distinguished by its ability to share physical graphics card resources across multiple virtual machines using paravirtualization and partitioning. It also provides specialized utilities for assigning PCIe devices and USB peripherals directly to guest machines for exclusive access.
The software covers a broad range of virtualization capabilities, including CPU topology optimization, processor pinning, and memory allocation. It also includes management for virtual networking through VLAN configuration and virtual switch administration, as well as storage operations like checkpoint management and virtual ISO creation.
The toolkit enables the implementation of hardware-rooted security such as memory encryption and Intel SGX enclaves, and supports nested virtualization by passing through CPU virtualization extensions.
