5.2.5.1. {vm-type}

Requirement: R-01455

target: VNF keyword: MUST updated: dublin validation_mode: static

When a VNF’s Heat Orchestration Template creates a Virtual Machine (i.e., OS::Nova::Server), each “class” of VMs MUST be assigned a VNF unique {vm-type}; where “class” defines VMs that MUST have the following identical characteristics: 1.) OS::Nova::Server resource property flavor value 2.) OS::Nova::Server resource property image value 3.) Cinder Volume attachments Each VM in the “class” MUST have the identical Cinder Volume configuration 4.) Network attachments and IP address requirements Each VM in the “class” MUST have the identical number of ports connecting to the identical networks and requiring the identical IP address configuration.

The {vm-type} will be used in a VNF’s Heat Orchestration Template’s

• Resource IDs

• Resource property parameter names

A VNF’s Heat Orchestration Template’s Resource property parameter that is associated with a unique Virtual Machine type MUST include {vm-type} as part of the parameter name with two exceptions:

1.) The Resource OS::Nova::Server property availability_zone parameter MUST NOT be prefixed with a common {vm-type} identifier,

2.) The Resource OS::Nova::Server mandatory and optional metadata parameters

• vnf_name

• vnf_id

• vf_module_id

• vf_module_name

• vf_module_index

• environment_context

• workload_context

MUST NOT be prefixed with a common {vm-type} identifier.

Requirements for specific resource property parameter names can be found in later sections of this document.

Requirement: R-98407

target: VNF keyword: MUST NOT updated: casablanca validation_mode: static

A VNF’s Heat Orchestration Template’s {vm-type} MUST contain only alphanumeric characters and/or underscores ‘_’ and MUST NOT contain any of the following strings: _int or int_ or _int_.

Requirement: R-48067

target: VNF keyword: MUST NOT updated: casablanca validation_mode: static

A VNF’s Heat Orchestration Template’s {vm-type} MUST NOT be a substring of {network-role}.

It may cause the VNF Validation Program validation-scripts project to produce erroneous error messages.

Requirement: R-32394

target: VNF keyword: MUST updated: casablanca validation_mode: static

A VNF’s Heat Orchestration Template’s use of {vm-type} in all Resource property parameter names MUST be the same case.

Requirement: R-46839

target: VNF keyword: MUST updated: casablanca validation_mode: static

A VNF’s Heat Orchestration Template’s use of {vm-type} in all Resource IDs MUST be the same case.

Requirement: R-36687

target: VNF keyword: SHOULD updated: casablanca

A VNF’s Heat Orchestration Template’s {vm-type} case in Resource property parameter names SHOULD match the case of {vm-type} in Resource IDs and vice versa.
