Hypervisors
===========
.. TODO: Add UML (User-Mode Linux) hypervisor to the following list when its
dedicated documentation is ready.

OpenStack Compute supports many hypervisors, which might make it difficult for
you to choose one. Most installations use only one hypervisor. However, you
can use :ref:`ComputeFilter` and :ref:`ImagePropertiesFilter` to schedule
different hypervisors within the same installation. The following links help
you choose a hypervisor. See :doc:`/user/support-matrix` for a detailed list
of features and support across the hypervisors.
The following hypervisors are supported:
* `KVM`_ - Kernel-based Virtual Machine. The virtual disk formats that it
supports is inherited from QEMU since it uses a modified QEMU program to
launch the virtual machine. The supported formats include raw images, the
qcow2, and VMware formats.
* `LXC`_ - Linux Containers (through libvirt), used to run Linux-based virtual
machines.
* `QEMU`_ - Quick EMUlator, generally only used for development purposes.
* `VMware vSphere`_ 5.1.0 and newer - Runs VMware-based Linux and Windows
images through a connection with a vCenter server.
* `Xen (using libvirt)`_ - Xen Project Hypervisor using libvirt as
management interface into ``nova-compute`` to run Linux, Windows, FreeBSD and
NetBSD virtual machines.
* `Hyper-V`_ - Server virtualization with Microsoft Hyper-V, use to run
Windows, Linux, and FreeBSD virtual machines. Runs ``nova-compute`` natively
on the Windows virtualization platform.
* `Virtuozzo`_ 7.0.0 and newer - OS Containers and Kernel-based Virtual
Machines supported via libvirt virt_type=parallels. The supported formats
include ploop and qcow2 images.
* `PowerVM`_ - Server virtualization with IBM PowerVM for AIX, IBM i, and Linux
workloads on the Power Systems platform.
* `zVM`_ - Server virtualization on z Systems and IBM LinuxONE, it can run Linux,
z/OS and more.
* `UML`_ - User-Mode Linux is a safe, secure way of running Linux versions and Linux
processes.
* `Ironic`_ - OpenStack project which provisions bare metal (as opposed to virtual)
machines.
Nova supports hypervisors via virt drivers. Nova has the following in tree
virt drivers:
* :oslo.config:option:`compute_driver` = ``libvirt.LibvirtDriver``
This driver runs on Linux and supports multiple hypervisor backends, which
can be configured via the :oslo.config:option:`libvirt.virt_type` config
option.
* :oslo.config:option:`compute_driver` = ``ironic.IronicDriver``
* :oslo.config:option:`compute_driver` = ``vmwareapi.VMwareVCDriver``
* :oslo.config:option:`compute_driver` = ``hyperv.HyperVDriver``
* :oslo.config:option:`compute_driver` = ``powervm.PowerVMDriver``
* :oslo.config:option:`compute_driver` = ``zvm.ZVMDriver``
* :oslo.config:option:`compute_driver` = ``fake.FakeDriver``
This driver does not spawn any virtual machines and therefore should only be
used during testing.
