LXD is an open source manager for virtual machines and system containers. It runs KVM-based VMs and LXC system containers that host a full Linux system, sets resource limits, and supports snapshots, live migration, projects for multi-user setups, hardware passthrough and OVN or SR-IOV networking. Instances start from images covering many Linux distributions and Windows VMs. LXD is software you install and operate yourself on your own servers, and commercial support is available through Ubuntu Pro.
LXD is developed by Canonical, the maker of Ubuntu, which is a privately held company headquartered in London, United Kingdom, and registered in the Isle of Man. The project is licensed under AGPL-3.0, with Apache-2.0 client libraries. Because you operate LXD yourself, workloads and data stay on the infrastructure you choose, including EU data centres. Note that the UK is outside the EU, so the vendor relationship, support contract and development roadmap sit under non-EU jurisdiction. Incus is a community fork of LXD for those who prefer independent governance.
