Running the VNF LCM instantiate using the sample vnf package fails

[Naoaki Horie]

I've confirmed that using the following sample VNF package, running the VNF LCM instantiate fails.
https://opendev.org/openstack/tacker/src/branch/master/samples/vnf_packages/sample_vnf_pkg.zip

I think that the uploaded VNF package should execute the VNF LCM instantiate normally.

additional information:

As show following log message when run the VNF LCM instantiate.

[Yasufumi Ogawa (yasufum)]

Could you explain WHAT is the problem? In addition, we need to understand HOW to see this error for inspecting it ourselves. I can roughly understand what is going on your environment, but not for the details. Thanks

[Toshiaki Takahashi (takahashi-tsc)]

In my understanding, this bug is fixed by proposed patch above as sample's bug.
But this bug also includes source code bug. Tacker always use glance with default checksum algorithm of glance setting.
Can I fix the bug? If OK, I create a new bug report and a patch.

[Toshiaki Takahashi (takahashi-tsc)]

Hmm... is hash algorithm fixed value in Glance setting? If so, it is only a issue of package...
I'll check it, but it may be not source code bug.

    Running the VNF LCM instantiate using the sample vnf package fails

    The CSAR file for VNF package registered as a sample fails to run
    the VNF LCM instantiate. The cause of this issue is typo and invalid
    definition for the VNFD. I think that the csar zip file for uploaded VNF
    package should be able to run the VNF LCM instantiate normally.
    Therefore, fix typo and invalid definition for the VNFD in the CSAR file.

    Also, fix to the following settings that has a dependent on environment
    because the current VNFD can only be run in the limited environment.

    * Change hash algorithm from sha-256 to sha-512 according
      the Glance default hash algorithm
    * Change from 8192 MB to 256 MB in the `min_ram` size of
      the VirtualStorage to work even in a low specification environment
    * Delete `CP1.properties.vnic_type` to work even under a virtual
      environment
