Prerequisites for Flavorless Provisioning

To enable flavorless VM creation in a Target Openstack environment, an end-user must first perform a one-time setup in OpenStack. This involves creating a special "base" flavor (eg: vjailbreak-base-flavor) that will act as a template for all flavorless migrations.

  • Create the Base Flavor: A flavor with 0 vCPUs and 0 RAM must be created.

    openstack flavor create --vcpus 0 --ram 0 --disk 60 --public vjailbreak-base-flavor or can be created from PCD UI.

Once this base flavor is created, users can select the "Use Dynamic Hotplug-Enabled Flavors" option during migration, and the system will automatically use this flavor to create custom-sized VMs based on the source VM's resources.
