Description

Develop virtualization solutions utilizing a minimalistic hypervisor that operates without the need for any external kernel extensions. The hypervisor offers C APIs, allowing for interaction with virtualization technologies directly in user space, eliminating the necessity of writing kernel extensions (KEXTs). Consequently, the applications designed with this framework can be distributed through the Mac App Store. Leverage this framework to create and manage hardware-accelerated virtual machines and virtual processors (VMs and vCPUs) from your authorized, sandboxed user-space application. The Hypervisor simplifies the concept of virtual machines as processes and treats virtual processors as threads. It is important to note that the Hypervisor framework relies on hardware capabilities to virtualize resources efficiently. For Apple silicon, this entails support for the Virtualization Extensions, while for Intel-based Macs, it necessitates systems equipped with an Intel VT-x feature set that includes Extended Page Tables (EPT) and Unrestricted Mode. This ensures the framework is optimized for performance and security across various hardware configurations.

Description

Lguest enables the operation of several instances of a 32-bit kernel simultaneously; by using the command modprobe lg, you can initiate it by running Documentation/lguest/lguest to establish a new guest. I encourage you to experiment with it as lguest is exceedingly straightforward to set up. Its utility is significant: I can boot kernels for testing purposes in less than a second, which is approximately ten times quicker than standard qemu and a hundred times faster than a traditional boot process. Moreover, since it employs a pty for the console, you're able to perform actions such as piping the output through grep. Lguest comprises a comprehensive kernel patch, which includes the launcher and is available in versions 2.6.23-git13 and later. The primary goal of lguest is to keep the guest isolated, preventing it from accessing the host directly, aside from virtual devices provided by the host, even if the guest is acting maliciously. Nevertheless, a potentially harmful guest kernel has the capability to pin host memory, limited to the volume allocated to the guest. While most images are configured to create virtual consoles like (/dev/tty0, etc.), the console for lguest is designated as /dev/hvc0, which adds a layer of distinction to its functionality. Additionally, this makes lguest a practical tool for developers who want to test kernel changes in a rapid and efficient manner without the overhead of a full virtualization solution.
