geni-lib has been updated to pull aggregate list from the Clearing house. Thus hardcoding aggregates is no longer needed.
The pull request
Updated to work with the latest geni-lib #22
proposes a fix for this issue.

Changing Line 45 to key_passphrase=False resolves the issue.

KeyboardInterrupt

All advertisement RSpecs are instantiated as geni-lib objects and then processed as a collection. This is memory intensive and can no longer be run on a VM with 1GB of RAM. It should be possible to instantiate each advertisement, run it through the processing pipeline, and then release it. This would greatly reduce runtime memory consumption.

This would require that the steps in the processing pipeline keep state as they process advertisements. These are currently functions that do not store state because they do not need to.

When using Al2S for GENI Stitching, Hairpin connections do not work . Jacks should disallow these
Hairpin connections - These are L2 connections between racks via the AL2S where in the racks involved. appear to be both connected to the same switch and port probably because there is a Regional involved that is invisible to GENI.

Running ./portal.sh throws this error. Commenting out the "import config" line - line 13 resolved the issue
