Interoperability of I&M Tools on GENI Racks

The primary goal of this effort is to get the GIMI and GEMINI tools working on both InstaGENI and ExoGENI racks. 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

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

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

GIMI on InstaGENI

Tools

• Sliver creation
  • Flack
  • Omni
• Presentation/Orchestration
  • Labwiki
  • OMF/OML

Resources

No known resource restrictions identified yet.

Images

• Create custom VM image
• Fedora
  • common Ubuntu image not expected until July

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

Configuration

• Convert postboot functionality into execute service script

Certificates

• Certificates not yet used for Labwiki

Testing

Browser Compatibility

	Mac	Ubuntu 12.04	Windows 7

GEMINI on ExoGENI

Tools

• Sliver creation
  • Read ​https://wiki.exogeni.net/doku.php?id=public:experimenters:start
  • Flack
  • Omni
• Presentation/Orchestration
  • GENI Desktop

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.

Images

• Create custom VM image
• Ezra and Hussam will determine the initial target OS
• Read ​https://geni-orca.renci.org/trac/wiki/neuca-images

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

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

Certificates

• All four types of certificates should work for GENI Desktop login and instrumentize

Tickets

These are tickets addressing issues that GEMINI has also encountered during testing/investigation:

​http://groups.geni.net/exogeni/ticket/109: SSH Keys: Only one ssh key is installed
