LXD is a next generation system container manager. It offers a user experience similar to virtual machines but using Linux containers instead. It's image based with pre-made images available for a wide number of Linux distributions and is built around a very powerful, yet pretty simple, REST API. To get a better idea of what LXD is and what it does, you can try it online! Then if you want to run it locally, take a look at our getting started guide. The LXD project was founded and is currently led by Canonical Ltd with contributions from a range of other companies and individual contributors. The core of LXD is a privileged daemon which exposes a REST API over a local unix socket as well as over the network (if enabled). Clients, such as the command line tool provided with LXD itself then do everything through that REST API. It means that whether you're talking to your local host or a remote server, everything works the same way.

QEMU is a generic and open-source machine emulator and virtualizer. Run operating systems for any machine, on any supported architecture. Run programs for another Linux/BSD target, on any supported architecture. Run KVM and Xen virtual machines with near-native performance. Guest memory dumps are now fully supported, along with pre-copy/post-copy migration and background guest snapshots. Support for nw DEVICE_UNPLUG_GUEST_ERROR to detect guest-reported hotplug failures. macOS hosts with Apple Silicon CPUs now support ‘hvf’ accelerator for AArch64 guests. M-profile MVE extension is now supported for Cortex-M55. AMD SEV guests now support measurement of kernel binary when doing direct kernel boot (not using a bootloader). Support for vhost-user and numa mem options across all boards.
