This hasn't been validated upstream and there doesn't appear to be anyone using it. It's time to drop support for this. This is mostly test and documentation damage, though there is some other cleanup going on, like the removal of the essentially noop 'pick_disk_driver_name' helper.

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.
|
|
|
|
* `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.
|
|
|
|
* `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.
