Description

IBM z/VM is a sophisticated operating system that features a hypervisor and virtualization technology, designed to effectively manage guest servers like Linux, z/OS, and z/TPF virtual machines, as well as Red Hat OpenShift on IBM Z and LinuxONE systems. This platform is capable of operating hundreds or even thousands of guest servers on a single IBM Z or LinuxONE server with remarkable efficiency and adaptability. It accommodates various machine images and architectures, which streamlines the migration process, eases application transitions, and enables the consolidation of multiple systems onto one server. By excelling in resource sharing among virtual machines, IBM z/VM provides outstanding scalability, security, and efficiency, resulting in significant cost reductions and creating a solid foundation for cognitive computing. Its implementation supports on-premises cloud computing within a hybrid cloud framework, allowing organizations to efficiently scale and manage thousands of Linux and container workloads. Moreover, it aids in maintaining continuous availability through IBM's robust resiliency offerings, ensuring that businesses can rely on their infrastructure without interruption. This versatility makes IBM z/VM a critical asset for modern enterprises looking to optimize their IT environments.

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.
