Virtuozzo
=========

Virtuozzo 7.0.0 (or newer), or its community edition OpenVZ, provides
both types of virtualization: Kernel Virtual Machines and OS Containers.
The type of instance to span is chosen depending on the ``hw_vm_type``
property of an image.

.. note::

   Some OpenStack Compute features may be missing when running with
   Virtuozzo as the hypervisor. See the `hypervisor support matrix
   <http://wiki.openstack.org/HypervisorSupportMatrix>`_ for details.

To enable Virtuozzo Containers, set the following options in
``/etc/nova/nova.conf`` on all hosts running the ``nova-compute``
service.

.. code-block:: ini

   compute_driver = libvirt.LibvirtDriver
   force_raw_images = False

   [libvirt]
   virt_type = parallels
   images_type = ploop
   connection_uri = parallels:///system
   inject_partition = -2
