You can associate metadata with an image using the --property key=value argument to glance image-create or glance image-update. For example: $ glance image-update img-uuid --property architecture=arm --property hypervisor_type=qemu If the following properties are set on an image, and the ImagePropertiesFilter scheduler filter is enabled (which it is by default), then the scheduler will only consider compute hosts that satisfy these properties: architecture The CPU architecture that must be supported by the hypervisor. For example, x86_64, arm, or ppc64. Run uname -m to get the architecture of a machine. We strongly recommend using the architecture data vocabulary defined by the libosinfo project for this purpose. Recognized values for this field are: alpha DEC 64-bit RISC armv7l ARM Cortex-A7 MPCore cris Ethernet, Token Ring, AXis - Code Reduced Instruction Set i686 Intel sixth-generation x86 (P6 micro architecture) ia64 Itanium lm32 Lattice Micro32 m68k Motorola 68000 microblaze Xilinx 32-bit FPGA (Big Endian) microblazeel Xilinx 32-bit FPGA (Little Endian) mips MIPS 32-bit RISC (Big Endian) mipsel MIPS 32-bit RISC (Little Endian) mips64 MIPS 64-bit RISC (Big Endian) mips64el MIPS 64-bit RISC (Little Endian) openrisc OpenCores RISC parisc HP Precision Architecture RISC parisc64 HP Precision Architecture 64-bit RISC ppc PowerPC 32-bit ppc64 PowerPC 64-bit ppcemb PowerPC (Embedded 32-bit) s390 IBM Enterprise Systems Architecture/390 s390x S/390 64-bit sh4 SuperH SH-4 (Little Endian) sh4eb SuperH SH-4 (Big Endian) sparc Scalable Processor Architecture, 32-bit sparc64 Scalable Processor Architecture, 64-bit unicore32 Microprocessor Research and Development Center RISC Unicore32 x86_64 64-bit extension of IA-32 xtensa Tensilica Xtensa configurable microprocessor core xtensaeb Tensilica Xtensa configurable microprocessor core (Big Endian) hypervisor_type The hypervisor type. Allowed values include: xen, qemu, kvm, lxc, uml, vmware, hyperv. vm_mode The virtual machine mode. This represents the host/guest ABI (application binary interface) used for the virtual machine. Allowed values are: 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. The following metadata properties are specific to the XenAPI driver: auto_disk_config A boolean option. If true, the root partition on the disk will be 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. os_type The operating system installed on the image. For example, linux or windows. The XenAPI driver contains logic that will take different actions depending on the value of the os_type parameter of the image. For example, for images where os_type=windows, 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. The following metadata properties are specific to the libvirt API driver: hw_video_model The video image driver used. Allowed values include: vga, cirrus, vmvga, xen and qxl. The following metadata properties are specific to the VMware API driver: vmware_adaptertype Indicates the virtual SCSI or IDE controller used by the hypervisor. Allowed values: lsiLogic, busLogic, ide vmware_ostype A VMware GuestID which describes the operating system installed in the image. This will be passed to the hypervisor when creating a virtual machine. See thinkvirt.com for a list of valid values. If this is not specified, it will default to otherGuest. vmware_image_version Currently unused, set it to 1. To assist end-users in utilizing images, you may wish to put additional common metadata on Glance images. By community agreement, the following metadata keys may be used across Glance installations for the purposes described, as follows. instance_uuid For snapshot images, this is the UUID of the server used to create this image. kernel_id The ID of image stored in Glance that should be used as the kernel when booting an AMI-style image. ramdisk_id The ID of image stored in Glance that should be used as the ramdisk when booting an AMI-style image. os_version The operating system version as specified by the distributor. os_distro The value of this property is the common name of the operating system distribution in all-lowercase. For this purpose, we use the same data vocabulary as the libosinfo project. Following are the recognized values for this property. In the interest of interoperability, please use only a recognized value for this field. The deprecated values are listed to assist you in searching for the recognized value.
