libvirt is an open source API, daemon and management tool for managing platform virtualization.[1] It can be used to manage Linux KVM, Xen, VMware ESX,qemu and other virtualization technologies. These APIs are widely used in Orchestration Layer for Hypervisors in the development of a cloud based solution.

  • Free software available under the GNU Lesser General Public License.
  • A long term stable C API
  • A set of bindings for common languages
  • A CIM provider for the DMTF virtualization schema
  • A QMF agent for the AMQP/QPid messaging system

libvirt supports:

  • The KVM/QEMU Linux hypervisor
  • The Xen hypervisor on Linux and Solaris hosts.
  • The LXC Linux container system
  • The OpenVZ Linux container system
  • The User Mode Linux paravirtualized kernel
  • The VirtualBox hypervisor
  • The VMware ESX and GSX hypervisors
  • The VMware Workstation and Player hypervisors
  • The Microsoft Hyper-V hypervisor
  • Virtual networks using bridging, NAT, VEPA and VN-LINK.
  • Storage on IDE/SCSI/USB disks, FibreChannel, LVM, iSCSI, NFS and filesystems

libvirt provides:

  • Remote management using TLS encryption and x509 certificates
  • Remote management authenticating with Kerberos and SASL
  • Local access control using PolicyKit
  • Zero-conf discovery using Avahi multicast-DNS
  • Management of virtual machines, virtual networks and storage
