Example implementations relate to generating virtualized network functions by identifying mappable elements and unmappable elements of a virtualized network function template based on a network function virtualization model. The mappable elements may be mapped to the network function virtualization model. The mappable elements may be translated based on the mapping. The unmappable elements are filtered based on a black-white list. The translated virtualized network function definition comprising the translated elements and the filtered elements is generated. The virtualized network function is generated based on the translated virtualized network function definition.
