Interoperability of I&M Tools on GENI Racks
1) Goals
The primary goal of this effort is to get the GIMI and GEMINI tools working on both InstaGENI and ExoGENI racks by GEC17.
To work toward this goal, we need to address items in the following areas:
- Tools
- Sliver creation (Flack/Flukes/Omni)
- Presentation/Orchestration (GENI Desktop/Labwiki)
- Archival (iRODS)
- Resources
- Images
- Rspecs
- Configuration
- initialize/instrumentize
- postboot scripts
- Testing
- What are the basic use cases?
- Certificates
- We should be able to use certificates issued by all four of these authorities for both sets of tools
- Utah emulab, UKY emulab, PGENI, GENI Portal
- We should be able to use certificates issued by all four of these authorities for both sets of tools
2) Mailing lists
These lists should be used for help on questions or issues with each of the racks. Subscribing to each of these lists will allow you to see the latest questions, answers, known issues and scheduled downtime related to each of the racks.
- ExoGENI: geni-orca-users@googlegroups.com
- InstaGENI: progoteni-users@googlegroups.com
3) Known differences between racks
ExoGENI | InstaGENI | |
Virtualization technology | KVM | openvz |
Images | requires separate filesystem/kernel/ramdisk images, highly recommended to add NEuca guest extensions, must run on KVM | Because VMs are openvz containers, must be same OS as hypervisor (Fedora) |
Data plane IPs | doesn't auto-assign IPs when not specified in request | auto-assigns IPs when not specified in request |
Login information | Not available in manifest until resources are active | Available as soon as resources are provisioned |
Hostnames | VMs or raw PCs do not have given hostnames configured | Hostnames set according to client-id in request |
See the GENI Racks RSpecs page for a summary of RSpec differences and observed behavior found in a walk-through of RSpec scenarios.
3) GIMI on InstaGENI
3.1) Tools
- Sliver creation
- Flack
- Omni
- Presentation/Orchestration
- Labwiki
- OMF/OML
3.2) Resources
No known resource restrictions identified yet.
3.3) Images
- Create custom VM image
- Fedora
- common Ubuntu image not expected until July
3.4) Rspecs
- Convert current tutorial RDF to rspec
- Should work if only nodes and links are specified
- Changes required
- images changed
- sliver-types changed (different virtualization)
- component managers removed
- Test the rspec on InstaGENI using both Flack and omni
3.5) Configuration
- Convert postboot functionality into execute service script
3.6) Certificates
- Certificates not yet used for Labwiki
3.7) Testing
Browser Compatibility

IE | N/A | N/A | |
Safari | N/A |
3.8) Issues
3.9) Demos
5/13/2013
- Labwiki instance running on InstaGENI slice
6/10/2013
7/8/2013
4) GEMINI on ExoGENI
4.1) Tools
- Sliver creation
- Read https://wiki.exogeni.net/doku.php?id=public:experimenters:start
- Flack
- Omni
- Presentation/Orchestration
- GENI Desktop
4.2) Resources
- Main concern is public IPs with access to certain ports for instrumentation
- Ilia confirms that all nodes have public IPs assigned. He will check if there are any port restrictions.
4.3) Images
- Create custom VM image
- Ezra and Hussam will determine the initial target OS
- Read https://geni-orca.renci.org/trac/wiki/neuca-images
- Starting with CentOS 6.3 shown on this page
4.4) Rspecs
- How does ExoGENI handle GEMINI extensions?
- Outstanding issue: ORCA is not able to pass thru extensions that is does not know about to the manifest. This includes Flack and GEMINI extensions.
- Let's discuss a more general 'measurement' extension for RSpecs usable by GIMI and GEMINI. We can add an NDL extension to support it in ORCA /ib
- Convert current tutorial rspec to RDF
- Test the RDF on ExoGENI using Flukes
- Test the rspec on ExoGENI using omni
- Test the rspec on ExoGENI using Flack when it is ready
4.5) Configuration
- Test the initialize/instrumentize scripts work on ExoGENI nodes
- Ahmed has tested converting ExoGENI manifest into UNIS schema
- Hussam reported earlier that GENI Desktop relies on location tags in the manifest for lat/long in topology map
- Ilia will look into possibly adding these to the ExoGENI rspec
4.6) Certificates
- All four types of certificates should work for GENI Desktop login and instrumentize
- Utah
- UKY
- GENI Portal
- PGENI
4.7) Testing
Certificate Compatibility
Login | Instrumentize | |
Utah Emulab | ||
UKY Emulab | ||
PGENI | ||
GENI Portal |

4.8) Issues
Issue ID Description Owner? Ticket Status 1 Slice expiry and Sliver expiry time dont match up. Coming? 2 The expiration_time attribute in the exogeni manifest reports values in two different formats. 3 SSH Keys: Only one ssh key is installed ExoGENI http://groups.geni.net/exogeni/ticket/109 4 url vs. name attribute for ExoGENI images ExoGENI/InstaGENI Ilia said he would make a change to converter to allow url. Discussions on instaGENI list propose to always using name attribute instead of url. 5 Flack canvas does not turn green when ExoGENI slice is ready ExoGENI Fixed in next deployment (week of 5/20) 6 EG does not assign IP address if not provided in the rspec ExoGENI 7 Problems deleting ExoGENI slices in Flack Flack 8 No way to map node logged into to node in manifest (IPs don't match, hostname doesn't match) Hostnames can be set with templated post-boot scripts 9 No way to map interface to a link in the manifest Ilia checking to see why mac address is not in the manifest rspec 10 No way to reboot an ExoGENI node (reboot from the command-line is unreliable) ExoGENI
Which of these are blocking progress for GEMINI interop?
