Quick answers
Frequently asked questions
1What hypervisors can libvirt manage?⌄
libvirt provides a unified management interface for a wide array of hypervisors, including KVM/QEMU, Xen, LXC, OpenVZ, VMware ESX/GSX/Workstation/Player, VirtualBox, Microsoft Hyper-V, and Bhyve. The project website details the specific capabilities and driver support for each.
2Is there a graphical user interface (GUI) for libvirt?⌄
While libvirt itself is primarily an API and command-line tool (`virsh`), several open-source and commercial GUIs are built on top of it. Notable examples include virt-manager (desktop application), Kimchi (web-based), and oVirt (datacenter virtualization management platform). The libvirt website often links to or discusses these frontends.
3How do I get started with developing against the libvirt API?⌄
Begin by reviewing the "API Reference" documentation on the website, focusing on the C API and the XML format for domain definitions. Download the latest development libraries, and explore the provided examples or tutorials linked from the documentation section to understand connection management, domain lifecycle, and event handling.
4What is the licensing model for libvirt?⌄
libvirt is open-source software distributed under the GNU Lesser General Public License (LGPL) version 2.1 or later. This allows for its use in both open-source and proprietary applications, provided the LGPL terms for linking and distribution are met.
5Where can I find community support or report bugs?⌄
The libvirt project offers support through its official mailing lists (e.g., libvirt-users for general questions, libvirt-devel for development discussions), which are accessible via the website. For reporting bugs or submitting feature requests, the project utilizes a dedicated bug tracking system, also linked from the main site.
