Boris Bobrov 1a88d35cb1 Also enable iommu for virtio controllers and video in libvirt 
Ie54fca066f33 added logic to libvirt/designer.py for enabling iommu
for certain devices where virtio is used.  This is required for AMD
SEV[0].  However it missed two cases.

Firstly, a SCSI controller can have the model as 'virtio-scsi', e.g.:

    <controller type='scsi' index='0' model='virtio-scsi'>

As with other virtio devices, here a child element needs to be added
to the config when SEV is enabled:

    <driver iommu="on" />

We do not need to cover the case of a controller with type
'virtio-serial' now, since even though it is supported by libvirt, it
is not currently used anywhere in Nova.

Secondly, a video device can be virtio, e.g. when vgpus are in use:

    <video>
        <model type='virtio'/>
    </video>

Also take this opportunity to clarify the corresponding documentation
around disk bus options.

OpenStack Nova

image

OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies, including: libvirt (KVM, Xen, LXC and more), Hyper-V, VMware, XenServer, OpenStack Ironic and PowerVM.

Use the following resources to learn more.

API

To learn how to use Nova's API, consult the documentation available online at:

For more information on OpenStack APIs, SDKs and CLIs in general, refer to:

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.

Further developer focused documentation is available at:

Other Information

During each Summit and Project Team Gathering, we agree on what the whole community wants to focus on for the upcoming release. The plans for nova can be found at:
