Cisco Enterprise Network Function Virtualization Infrastructure Software Configuration Guide, Release 3.6.1

VM Image Packaging is a tool for converting qcow2 and img images into a tar.gz format with additional properties and profiles. VM image packaging can be done in two ways:

  • VM Image Packaging Utility: This is an enhanced packaging process that allows the VM owner to run the nfvpt.py utility as a command with a combination of parameters to package the VM.

  • Standard Image Packaging: This is a manual process in which a raw disk image (qcow2, img) is packaged along with the image properties file and bootstrap files (if needed) into a TAR archive file.

VM Image Packaging Utility

A VM image package is a TAR archive file with the root disk image and other descriptor files. This packaging method simplifies the process of a VM image registration and deployment. The attributes specified for the image enable resource requirement specification, creation of VM profiles, and a host of other properties for the VM.

The Cisco Enterprise NFVIS VM image packaging tool, nfvpt.py, helps VM owners package their VMs. The tool takes one or more qcow2 images (raw disk file) as the input file along with VM specific properties, bootstrap configuration files (if any), and generates a compressed TAR file.

Contents

The VM image packaging utility contains the following:

  • nfvpt.py—It is a python based packaging tool that bundles the VM raw disk image/s along with VM specific properties.

  • image_properties_template.xml—This is the template file for the VM image properties file, and has the parameters with default values. If the user provides new values to these parameters while creating the VM package, the default values get replaced with the user-defined values.

  • nfvis_vm_packaging_utility_examples.txt—This file contains examples on how to use the image packaging utility to package a VM image.

Usage

To get the list of parameters that can be included in the command, and to get an explanation of each of the parameters, run the help command for the tool.

VM Packaging Utility Usage Examples

Given below are the contents of the file nfvis_vm_packaging_utility_examples.txt:

Example 1: Usage for TinyLinux


nfvpt.py -o TinyLinux -i TinyLinux.qcow2 -n TinyLinux -t linux -r 1.0 --monitored false 
--min_vcpu 1 --max_vcpu 2 --min_mem 1024 --max_mem 1024 --min_disk 1 --max_disk 2 
--vnic_max 1 --optimize false

Example 2: Usage for ASAv


Note

The bootstrap filename has to be day0-config. This cannot be modified as ASAv looks for the exact filename.



nfvpt.py -o asav961-201 -i asav961-201.qcow2 -n ASAv -t firewall -r 961-201 --monitored true --bootstrap day0-config:filename1 
--min_vcpu 1 --max_vcpu 4 --min_mem 1024 --max_mem 8192 --min_disk 8 --max_disk 16 --vnic_max 8 --optimize true 
--profile ASAv5,"ASAv5 profile",1,1024,8192 --profile ASAv10,"ASAv10 profile",1,4096,8192 --profile ASAv30,"ASAv30 profile",4,8192,16384
--default_profile ASAv5 

Example 3: Usage for ISRv


Note

The bootstrap filename has to be ovf-env.xml . This cannot be modified as ISRv looks for the exact filename.



nfvpt.py -o isrv.16.03.01 -i isrv-universalk9.16.03.01.qcow2 -n ISRv.16.03.01 -t ROUTER -r 16.03.01 --monitored true --privileged true 
--bootstrap ovf-env.xml:file1,ios-xe.txt:file2 --min_vcpu 2 --max_vcpu 8 --min_mem 4096 --max_mem 8192 --min_disk 8 --max_disk 8 
--vnic_max 8 --optimize true --profile ISRv-small,"ISRv small profile",2,4096,8192 --profile ISRv-medium,"ISRv medium profile",4,4096,8192 
--default_profile ISRv-small --sriov_list igb,igbvf,i40evf --custom tech_package,ax 

Example 4: Usage for a third party VM with config drive (ISO) mounted at specific path on the VM:

nfvpt.py -o test.1.0 -i test-1.0.qcow2 -n TEST -t OTHER -r 1.0 --monitored true --privileged true
--bootstrap /:bootstrap.xml,/license/lic.txt:license.txt --min_vcpu 2 --max_vcpu 8 --min_mem 4096 --max_mem 8192
--min_disk 8 --max_disk 8 --vnic_max 8 --optimize true --profile small,"small  profile",2,4096,8192 
--profile medium,"medium profile",4,4096,8192 --default_profile small
 

In this case, test.1.0.pkg : bootstrap.xml gets mounted as bootstrap.xml at the root, and the license.txt gets mounted as /license/lic.txt.

Standard VM Image Packaging

The standard VM packaging is based on the Open Virtualization Format (OVF) packaging standard, in which a single file is distributed in open virtualization appliance (OVA) format. The VM image is shared using a TAR archive file with the root disk image and descriptor files.


Note

Cisco Enterprise NFVIS supports VM packaging in .tar.gz (compressed form of OVA) format. Ensure that all supported third party VM images are available in the supported format.


Generating a VM Package

Package files are provided for Cisco ISRv, Cisco ASAv, and tiny Linux and Windows server 2000. Vendors are responsible for packaging all third party VMs in the supported format.

  1. Create a VM qcow2 image.

  2. Create an image_properties.xml file with the VM properties. Ensure that you add all mandatory fields. Include the profiles supported for the VM in this file, and select one default profile. If you do not want to monitor the VM bootup, make the bootup time as -1.

  3. Create bootstrap-config or day0-config, if any bootstrap configuration is required for the VM. If the bootstrap configuration requires inputs from the user, use the tokens in the xml or text file. These tokens are populated during the VM deployment with the provided data.


    Note

    A VM deployment may fail, if there are tokens in the configuration, and the user does not provide the token values in the deployment payload.


  4. Create a package.mf file, which lists all the files to be bundled into the .tar.gz file along with checksums.

  5. Generate the packaging file using "tar -cvzf ova_file_name list_of_files_to_be_bundled".

    For example, tar -cvzf isrv.tar.gz isrv-universalk9.03.16.02.S.155-3.S1a-ext-serial.qcow2 image_properties.xml isr_ovf_env.xml package.mf.
