{vm-type}
-----------------
.. req::
:id: R-01455
:target: VNF
:keyword: MUST
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 property flavor value
2.) OS::Nova::Server 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 the identical number
of ports connecting to the identical networks and requiring the
identical IP address configuration.
.. req::
:id: R-82481
:target: VNF
:keyword: MUST
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 eight mandatory and optional metadata
parameters (vnf_name, vnf_id, vf_module_id, vf_module_name, vm_role,
vf_module_index, environment_context, workload_context) **MUST NOT**
be prefixed with a common '{vm-type}' identifier.
.. req::
:id: R-66729
:target: VNF
:keyword: MUST
A VNF's Heat Orchestration Template's Resource that is
associated with a unique Virtual Machine type **MUST** include
'{vm-type}' as part of the resource ID.
.. req::
:id: R-98407
:target: VNF
:keyword: MUST NOT
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\_'.
.. req::
:id: R-48067
:target: VNF
:keyword: MUST NOT
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.
.. req::
:id: R-32394
:target: VNF
:keyword: MUST
A VNF's Heat Orchestration Template's use of '{vm-type}'
in all Resource property parameter names **MUST** be the same case.
.. req::
:id: R-46839
:target: VNF
:keyword: MUST
A VNF's Heat Orchestration Template's use of
'{vm-type}' in all Resource IDs **MUST** be the same case.
.. req::
:id: R-36687
:target: VNF
:keyword: SHOULD
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.
