  <node virtual_id="geni2"

Note: The tarfile and startup_command are required as stated by the S3 user guide.

The slice and sliver were created and the output was captured to create the manifest file which is required by the S3 setup:

lnevers@sendaria:~/gcf-1.2$ ./src/ createslice s3-slice
INFO:omni:Loading config file omni_config
INFO:omni:Using control framework pgeni
Created slice with Name s3-slice, URN
lnevers@sendaria:~/gcf-1.2$ ./src/ -a -n createsliver s3-slice pg.rspec > s3-manifest

Now Upload Manifest File and select node addresses:

This results in a error which is being worked on.
