Description

KVM, which stands for Kernel-based Virtual Machine, serves as a comprehensive virtualization solution for Linux systems operating on x86 hardware equipped with virtualization capabilities (such as Intel VT or AMD-V). It comprises a loadable kernel module, known as kvm.ko, that underpins the essential virtualization framework, along with a processor-specific module, either kvm-intel.ko or kvm-amd.ko. By utilizing KVM, users can operate several virtual machines that run unaltered Linux or Windows operating systems. Each virtual machine is allocated its own set of virtualized hardware components, including a network interface card, storage, graphics adapter, and more. KVM is an open-source project, with its kernel component integrated into the mainline Linux kernel since version 2.6.20, while the userspace aspect has been incorporated into the mainline QEMU project starting from version 1.3. This integration enables widespread deployment and support for various virtualization applications and services.

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.
