Image service property keys
===========================
The following keys, together with the components to which they are specific,
can be used with the property option for both the
:command:`openstack image set` and :command:`openstack image create` commands.
For example:
.. code-block:: console
$ openstack image set IMG-UUID --property architecture=x86_64
.. note::
Behavior set using image properties overrides behavior set using flavors.
For more information, refer to the `Manage images
<https://docs.openstack.org/glance/latest/admin/manage-images.html>`_
in the OpenStack Administrator Guide.

cap than that defined in the network they are attached to. This factor
is multiplied by the ``rxtx_base`` property of the network. The
``rxtx_base`` property defaults to ``1.0``, which is the same as the
attached network. This parameter is only available for Xen or NSX based

- ``os_version``
- The operating system version as specified by the distributor.
- Valid version number (for example, ``11.10``).
* - All
- ``os_secure_boot``
- Secure Boot is a security standard. When the instance starts,
Secure Boot first examines software such as firmware and OS by their
signature and only allows them to run if the signatures are valid.
For Hyper-V: Images must be prepared as Generation 2 VMs. Instance must
also contain ``hw_machine_type=hyperv-gen2`` image property. Linux
guests will also require bootloader's digital signature provided as
``os_secure_boot_signature`` and
``hypervisor_version_requires'>=10.0'`` image properties.
- * ``required`` - Enable the Secure Boot feature.
* ``disabled`` or ``optional`` - (default) Disable the Secure Boot
feature.
* - All
- ``ramdisk_id``
- The ID of image stored in the Image service that should be used as the
ramdisk when booting an AMI-style image.
- Valid image ID.
* - All
- ``vm_mode``
- The virtual machine mode. This represents the host/guest ABI
(application binary interface) used for the virtual machine.
- * ``hvm`` - Fully virtualized. This is the mode used by QEMU and KVM.
* ``xen`` - Xen 3.0 paravirtualized.
* ``uml`` - User Mode Linux paravirtualized.
* ``exe`` - Executables in containers. This is the mode used by LXC.
* - libvirt API driver
- ``hw_cpu_sockets``
- The preferred number of sockets to expose to the guest.
- Integer.
* - libvirt API driver
- ``hw_cpu_cores``
- The preferred number of cores to expose to the guest.
- Integer.
* - libvirt API driver
- ``hw_cpu_threads``
- The preferred number of threads to expose to the guest.
- Integer.
* - libvirt API driver
- ``hw_disk_bus``
- Specifies the type of disk controller to attach disk devices to.
- One of ``scsi``, ``virtio``, ``uml``, ``xen``, ``ide``, or ``usb``.
* - libvirt API driver
- ``hw_rng_model``
- Adds a random-number generator device to the image's instances. The
cloud administrator can enable and control device behavior by
configuring the instance's flavor. By default:
* The generator device is disabled.
* ``/dev/random`` is used as the default entropy source. To specify a
physical HW RNG device, use the following option in the nova.conf
file:
.. code-block:: ini
rng_dev_path=/dev/hwrng
- ``virtio``, or other supported device.
* - libvirt API driver, Hyper-V driver
- ``hw_machine_type``
- For libvirt: Enables booting an ARM system using the specified machine
type. By default, if an ARM image is used and its type is not specified,
Compute uses ``vexpress-a15`` (for ARMv7) or ``virt`` (for AArch64)
machine types.
For Hyper-V: Specifies whether the Hyper-V instance will be a generation
1 or generation 2 VM. By default, if the property is not provided, the
instances will be generation 1 VMs. If the image is specific for
generation 2 VMs but the property is not provided accordingly, the
instance will fail to boot.
- For libvirt: Valid types can be viewed by using the
:command:`virsh capabilities` command (machine types are displayed in
the ``machine`` tag).
For hyper-V: Acceptable values are either ``hyperv-gen1`` or
``hyperv-gen2``.
* - libvirt API driver, XenAPI driver
- ``os_type``
- The operating system installed on the image. The ``libvirt`` API driver
and ``XenAPI`` driver contains logic that takes different actions
depending on the value of the ``os_type`` parameter of the image.
For example, for ``os_type=windows`` images, it creates a FAT32-based
swap partition instead of a Linux swap partition, and it limits the
injected host name to less than 16 characters.
- ``linux`` or ``windows``.
* - libvirt API driver
- ``hw_scsi_model``
- Enables the use of VirtIO SCSI (``virtio-scsi``) to provide block
device access for compute instances; by default, instances use VirtIO
Block (``virtio-blk``). VirtIO SCSI is a para-virtualized SCSI
controller device that provides improved scalability and performance,
and supports advanced SCSI hardware.
- ``virtio-scsi``
* - libvirt API driver
- ``hw_serial_port_count``
- Specifies the count of serial ports that should be provided. If
``hw:serial_port_count`` is not set in the flavor's extra_specs, then
any count is permitted. If ``hw:serial_port_count`` is set, then this
provides the default serial port count. It is permitted to override the
default serial port count, but only with a lower value.
- Integer
* - libvirt API driver
- ``hw_video_model``
- The video image driver used.
- ``vga``, ``cirrus``, ``vmvga``, ``xen``, or ``qxl``.
* - libvirt API driver
- ``hw_video_ram``
- Maximum RAM for the video image. Used only if a ``hw_video:ram_max_mb``
value has been set in the flavor's extra_specs and that value is higher
than the value set in ``hw_video_ram``.
- Integer in MB (for example, ``64``).
* - libvirt API driver
- ``hw_watchdog_action``
- Enables a virtual hardware watchdog device that carries out the
specified action if the server hangs. The watchdog uses the
``i6300esb`` device (emulating a PCI Intel 6300ESB). If
``hw_watchdog_action`` is not specified, the watchdog is disabled.
- * ``disabled`` - (default) The device is not attached. Allows the user to
disable the watchdog for the image, even if it has been enabled using
the image's flavor.
* ``reset`` - Forcefully reset the guest.
* ``poweroff`` - Forcefully power off the guest.
* ``pause`` - Pause the guest.
* ``none`` - Only enable the watchdog; do nothing if the server hangs.
* - libvirt API driver
- ``os_command_line``
- The kernel command line to be used by the ``libvirt`` driver, instead
of the default. For Linux Containers (LXC), the value is used as
arguments for initialization. This key is valid only for Amazon kernel,
``ramdisk``, or machine images (``aki``, ``ari``, or ``ami``).
-
* - libvirt API driver and VMware API driver
- ``hw_vif_model``
- Specifies the model of virtual network interface device to use.
- The valid options depend on the configured hypervisor.
* ``KVM`` and ``QEMU``: ``e1000``, ``ne2k_pci``, ``pcnet``,
``rtl8139``, and ``virtio``.
* VMware: ``e1000``, ``e1000e``, ``VirtualE1000``, ``VirtualE1000e``,
``VirtualPCNet32``, ``VirtualSriovEthernetCard``, and
``VirtualVmxnet``.
* Xen: ``e1000``, ``netfront``, ``ne2k_pci``, ``pcnet``, and
``rtl8139``.
* - libvirt API driver
- ``hw_vif_multiqueue_enabled``
- If ``true``, this enables the ``virtio-net multiqueue`` feature. In
this case, the driver sets the number of queues equal to the number
of guest vCPUs. This makes the network performance scale across a
number of vCPUs.
- ``true`` | ``false``
* - libvirt API driver
- ``hw_boot_menu``
- If ``true``, enables the BIOS bootmenu. In cases where both the image
metadata and Extra Spec are set, the Extra Spec setting is used. This
allows for flexibility in setting/overriding the default behavior as
needed.
- ``true`` or ``false``
* - VMware API driver
- ``vmware_adaptertype``
- The virtual SCSI or IDE controller used by the hypervisor.
- ``lsiLogic``, ``lsiLogicsas``, ``busLogic``, ``ide``, or
``paraVirtual``.
* - VMware API driver
- ``vmware_ostype``
- A VMware GuestID which describes the operating system installed in
the image. This value is passed to the hypervisor when creating a
virtual machine. If not specified, the key defaults to ``otherGuest``.
- See `thinkvirt.com <http://www.thinkvirt.com/?q=node/181>`_.
* - VMware API driver
- ``vmware_image_version``
- Currently unused.
- ``1``
* - XenAPI driver
- ``auto_disk_config``
- If ``true``, the root partition on the disk is automatically resized
before the instance boots. This value is only taken into account by
the Compute service when using a Xen-based hypervisor with the
``XenAPI`` driver. The Compute service will only attempt to resize if
there is a single partition on the image, and only if the partition
is in ``ext3`` or ``ext4`` format.
- ``true`` or ``false``
