Without third-party kernel extensions, you can build virtualization solutions on top a lightweight hypervisor. Hypervisor offers C APIs that allow you to interact with virtualization technologies in user-space, without the need for kernel extensions (KEXTs). The framework allows you to create apps that are compatible with distribution on the Mac App Store. This framework can be used to create and control hardware-facilitated Virtual Machines and Virtual Processors (VMs, vCPUs) using your entitled, sandboxed user-space process. Hypervisor abstracts virtual machine processes and virtual processors threads. To virtualize hardware resources, Hypervisor requires hardware support. This includes the Virtualization Extensions on Apple silicon. The framework supports Intel-based Mac computers with an Intel VTX feature set, which includes Extended Page Tables and Unrestricted Mode.

Lguest allows you to run multiple copies of the same 32-bit kernel, simply modprobe lg, then run Documentation/lguest/lguest to create a new guest. This is something I recommend you do. Lguest is very easy to set up. It's also very useful: I can test-boot Kernels with it in less that a second, which is about 10x faster then basic qemu and 100x faster as a real boot. It uses a pty console so you can pipe it through grep. lguest is a single kernel patch that includes the launcher. It is in 2.6.23.git13 and higher. Lguest is designed to isolate the guest from the host, so that it can't reach outside (except for virtual devices supplied to the host). A malicious guest kernel can pin host memory, but only up to the amount allowed to it. Images are usually set up to create console virtual consoles (/dev/tty0 etc), however, the lguest console can be found at /dev/hvc0.

LXD is the next generation system container manager. It provides a similar user experience to virtual machines, but with Linux containers instead. It is image-based and has pre-made images for a variety of Linux distributions. It is built around a powerful, but simple, REST API. You can get a better understanding of LXD and its capabilities by trying it online. If you are interested in running it locally, then take a look to our getting started guide. Canonical Ltd founded the LXD project and leads it today. Contributions from other companies and individuals are also welcome. LXD's core is a privileged daemon that exposes a REST API both over a local socket and over the network (if it is enabled). Clients, such the command line tool included with LXD, then access that REST API to perform all tasks. This means that everything works the same regardless of whether you are talking to a local host or remote server.
