openstack.image.v2.image¶

The Image Class¶

The Image class inherits from Resource.

class openstack.image.v2.image.Image(_synchronized=False, connection=None, **attrs)¶

The base resource

Parameters:	_synchronized (bool) – This is not intended to be used directly. See new() and existing(). connection (openstack.connection.Connection) – Reference to the Connection being used. Defaults to None to allow Resource objects to be used without an active Connection, such as in unit tests. Use of self._connection in Resource code should protect itself with a check for None.

checksum¶

Hash of the image data used. The Image service uses this value for verification.

container_format¶

The container format refers to whether the VM image is in a file format that also contains metadata about the actual VM. Container formats include OVF and Amazon AMI. In addition, a VM image might not have a container format - instead, the image is just a blob of unstructured data.

created_at¶

The date and time when the image was created.

disk_format¶

Valid values are: aki, ari, ami, raw, iso, vhd, vdi, qcow2, or vmdk. The disk format of a VM image is the format of the underlying disk image. Virtual appliance vendors have different formats for laying out the information contained in a VM disk image.

is_hidden¶

This field controls whether an image is displayed in the default image-list response

is_protected¶

Defines whether the image can be deleted. Type: bool

hash_algo¶

The algorithm used to compute a secure hash of the image data for this image

hash_value¶

The hexdigest of the secure hash of the image data computed using the algorithm whose name is the value of the os_hash_algo property.

min_disk¶

The minimum disk size in GB that is required to boot the image.

min_ram¶

The minimum amount of RAM in MB that is required to boot the image.

name¶

The name of the image.

owner_id¶

The ID of the owner, or project, of the image.

properties¶

Properties, if any, that are associated with the image.

size¶

The size of the image data, in bytes.

store¶

When present, Glance will attempt to store the disk image data in the backing store indicated by the value of the header. When not present, Glance will store the disk image data in the backing store that is marked default. Valid values are: file, s3, rbd, swift, cinder, gridfs, sheepdog, or vsphere.

status¶

The image status.

tags¶

Tags, if any, that are associated with the image.

updated_at¶

The date and time when the image was updated.

virtual_size¶

The virtual size of the image.

visibility¶

The image visibility.

file¶

The URL for the virtual machine image file.

locations¶

A list of URLs to access the image file in external store. This list appears if the show_multiple_locations option is set to true in the Image service’s configuration file.

direct_url¶

The URL to access the image file kept in external store. It appears when you set the show_image_direct_url option to true in the Image service’s configuration file.

url¶

The URL to access the image file kept in external store.

metadata¶

The location metadata.

architecture¶

The CPU architecture that must be supported by the hypervisor.

hypervisor_type¶

The hypervisor type. Note that qemu is used for both QEMU and KVM hypervisor types.

instance_type_rxtx_factor¶

Optional property allows created servers to have a different bandwidth cap than that defined in the network they are attached to.

instance_uuid¶

create this image.

needs_config_drive¶

Specifies whether the image needs a config drive. mandatory or optional (default if property is not used).

kernel_id¶

The ID of an image stored in the Image service that should be used as the kernel when booting an AMI-style image.

os_distro¶

The common name of the operating system distribution in lowercase

os_version¶

The operating system version as specified by the distributor.

needs_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.

ramdisk_id¶

The ID of image stored in the Image service that should be used as the ramdisk when booting an AMI-style image.

vm_mode¶

The virtual machine mode. This represents the host/guest ABI (application binary interface) used for the virtual machine.

hw_cpu_sockets¶

The preferred number of sockets to expose to the guest.

hw_cpu_cores¶

The preferred number of cores to expose to the guest.

hw_cpu_threads¶

The preferred number of threads to expose to the guest.

hw_disk_bus¶

Specifies the type of disk controller to attach disk devices to. One of scsi, virtio, uml, xen, ide, or usb.

hw_rng_model¶

Adds a random-number generator device to the image’s instances.

hw_machine_type¶

For libvirt: Enables booting an ARM system using the specified machine type. For Hyper-V: Specifies whether the Hyper-V instance will be a generation 1 or generation 2 VM.

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).

hw_serial_port_count¶

Specifies the count of serial ports that should be provided.

hw_video_model¶

The video image driver used.

hw_video_ram¶

Maximum RAM for the video image.

hw_watchdog_action¶

Enables a virtual hardware watchdog device that carries out the specified action if the server hangs.

os_command_line¶

The kernel command line to be used by the libvirt driver, instead of the default.

hw_vif_model¶

Specifies the model of virtual network interface device to use.

is_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.

is_hw_boot_menu_enabled¶

If true, enables the BIOS bootmenu.

vmware_adaptertype¶

The virtual SCSI or IDE controller used by the hypervisor.

vmware_ostype¶

A VMware GuestID which describes the operating system installed in the image.

has_auto_disk_config¶

If true, the root partition on the disk is automatically resized before the instance boots.

os_type¶

The operating system installed on the image.

os_admin_user¶

The operating system admin username.

hw_qemu_guest_agent¶

If true, QEMU guest agent will be exposed to the instance.

os_require_quiesce¶

If true, require quiesce on snapshot via QEMU guest agent.

deactivate(session)¶

Deactivate an image

Note: Only administrative users can view image locations for deactivated images.

reactivate(session)¶

Reactivate an image

Note: The image must exist in order to be reactivated.

upload(session)¶

Upload data into an existing image

import_image(session, method='glance-direct', uri=None)¶

Import Image via interoperable image import process

download(session, stream=False)¶

Download the data contained in an image

classmethod find(session, name_or_id, ignore_missing=True, **params)¶

Find a resource by its name or id.

Parameters:	session (Adapter) – The session to use for making this request. name_or_id – This resource’s identifier, if needed by the request. The default is None. ignore_missing (bool) – When set to False ResourceNotFound will be raised when the resource does not exist. When set to True, None will be returned when attempting to find a nonexistent resource. params (dict) – Any additional parameters to be passed into underlying methods, such as to existing() in order to pass on URI parameters.
Returns:	The Resource object matching the given name or id or None if nothing matches.
Raises:	openstack.exceptions.DuplicateResource if more than one resource is found for this request.
Raises:	openstack.exceptions.ResourceNotFound if nothing is found and ignore_missing is False.
