# 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 Feature Support Matrix for details.

## Configuration

To enable LXC, configure `DEFAULT.compute_driver` = `libvirt.LibvirtDriver` and `libvirt.virt_type` = `parallels`. For example:

    [DEFAULT]
    compute_driver = libvirt.LibvirtDriver
    force_raw_images = False

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

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

    [DEFAULT]
    compute_driver = libvirt.LibvirtDriver

    [libvirt]
    virt_type = parallels
    images_type = qcow2
    connection_uri = parallels:///system
