Updating the flavor for an OpenStack cloud configuration

You can update the flavor that is configured for the cloud.

Procedure

  1. Set the following required values:
    • Name
    • Virtual CPUs
    • Memory (MB)
    • Storage (GB)
    • Swap(MB) This option is only supported for KVM deployments.
    Notes:
    • When updating the flavor, only integers are valid for the processor, memory, storage, and swap sizes. Any fractional data is omitted.
    • After a flavor is created or updated, it can be used to deploy OpenStack images. However, the new or updated flavor might not be immediately available when configuring an image. If this occurs, you can reset the image configuration to the default values in order to pick up the flavor changes made in the cloud. For more information, see Configuring image deployment properties.
    • Flavors with a storage size of 0 have special meaning in OpenStack and are not supported by numerous hypervisors such as Hyper-V. Hypervisors that do support such flavors use the size of the image as the storage size when provisioning a virtual machine from the image.
    • Out of band modifications to the PowerVCCompute templates are not synchronized to IBM® Cloud Manager with OpenStack. If a flavor is updated in PowerVC, the change in values is not reflected in IBM Cloud Manager with OpenStack.
  2. Optional: Specify extra specifications.
