Description

OSM searches for suitable flavors among existing ones in the Openstack clouds during new VM instance creation according to the descriptor. If the suitable flavor could not be found, the new flavor is created. There is a requirement from community to use existing flavors which may include specific metadata.

This feature allows the usage of a specific flavor in case the flavor-id is provided at instantiation time. By this feature, manually created flavors which have complex EPA configuration could be used for VM creation.

Demo or definition of done

• Instantiation parameters are specified during NS instantiation for VNF/VDU basis using options --flavor_id.
• NS is instantiated.
• Given flavor-id should be used to create the specified virtual machine.

This work is considered done when all the implementations, tests and documentation is contributed to use this feature.
