        • property keys

      When working with IBM Bluemix Private Cloud with Red Hat the following keys can be used with the property option for both the glance image-update and glance image-create commands.

      $ glance image-update IMG-UUID --property architecture=x86_64

      Note: Behavior set using image properties overrides behavior set using flavors.

      Property Keys

      Applies To Key Description Supported values
      All architecture The CPU architecture that must be supported by the hypervisor. For example, x86_64 is the currently supported CPU type. x86_64 -64-bit extension of IA-32
      All instance_uuid For snapshot images, this is the UUID of the server used to create this image. Valid server UUID
      All 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. Valid image ID
      All os_distro The common name of the operating system distribution in lowercase (uses the same data vocabulary as the libosinfo project). Specify only a recognized value for this field. Values are listed below to assist you in searching for the recognized value. (See List Below)
      All os_version The operating system version as specified by the distributor. Version number (for example, “11.10”)
      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.
      libvirt API driver hw_disk_bus Specifies the type of disk controller to attach disk devices to. scsi, virtio, ide, or usb.
      libvirt API driver hw_qemu_guest_agent Guest agent support. If set to yes, and if qemu-ga is also installed, file systems can be quiesced (frozen) and snapshots created automatically. yes / no
      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, And /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: rng_dev_path=/dev/hwrng virtio, or other supported device.
      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_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 -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. The default value for this parameter is disabled. 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 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.
