Requests for any sliver results in "No matching global declaration available for the validation root"

[lnevers@bbn.com]

Any request to create a sliver at the BBN SM using any RSpecs that I have used successfully in the past, now results in the following failure:

  Result Summary: Slice urn:publicid:IDN+pgeni.gpolab.bbn.com+slice+lnslice expires on 2012-06-23 15:37:08 UTC

Victor tells me we have not changed anything in FOAM/FV setup recently. Perhaps Nick can answer this.

[jbs@bbn.com]

Oh, I missed that this was a FOAM thing; I can probably help.

Luisa, does your rspec validate with rspeclint?

[jbs@bbn.com]

Also, didn't you just now create a sliver at BBN ExoGENI FOAM, successfully?

The RSpec used is a 2 VM shared VLAN RSPec that I have used in the past:

Also rspeclint never completes successfully for the RSpecs even when they work:

That's not a FOAM rspec.

[jbs@bbn.com]

Sorry, juggling too many things: To be less terse, that rspec isn't a FOAM rspec, but you're sending it to FOAM ("Asked ​https://bbn-hn.exogeni.net:3626/foam/gapi/1 to reserve resources"), and FOAM is saying "that's not a FOAM rspec". It passes rspeclint because it's a valid *ORCA* rspec; you need to send it to ORCA, not to FOAM.

I have been doing a lot of OpenFlow? testing. I am trying to run the following experiment, which has two parts:

1. Site Hosts on Shared OF VLAN 1750 via ExoGENI FOAM/OF (slice
2. ExoGENI VMs on Shared VLAN 1750 via ExoGENI FOAM/OF (*)

I am running 1 without problem, and trying to add part2 above. The failure is occurring with part2. Also there is another experiment running "experiment 2" which is using site hosts on multi-point non-OF VLAN 3705 via ExoGENI RACK.

As far as rspeclint goes, try replacing "​http://www.protogeni.net/resources/rspec/ext/shared-vlan/1" with "​http://www.protogeni.net/resources/rspec/ext/shared-vlan/1/request.xsd" in the "xsi:schemaLocation" declaration.

Note: do not change the "xmlns:s" declaration, that looks correct.

[jbs@bbn.com]

Seriously, the problem here is that you're sending an ORCA rspec to FOAM.

[ibaldin@renci.org]

Also please note that Orca does not support (as a matter of policy) users requesting random vlans (like 3705 above). Only VLANs explicitly known as 'shared' to the Orca AM can be explicitly requested by users. Your request for 3705 will not succeed.

Agreed. VLAN 3705 is part of EG-EXP-5, the "campus resources" test. We don't expect to be able to put ORCA resources onto VLAN 3705.

Sigh!!! I had my OpenFlow? hat on, Argh!!

I kept trying to get my OpenFlow? shared VLAN in the rack from the FOAM controller, while I should have been requesting it from the SM!! Will close this ticket!

This syntax came from email on June 13th about shared-vlan support. I will update all my RSpec to capture this.

Are there example on any of the wikis that use that original example?

[ibaldin@renci.org]

If vlan 3705 is special, we need to configure it as such in Orca substrate description. Since we will be redeploying Orca on Monday,please let us know any other changes we need to make.

[jbs@bbn.com]

I don't think we need ORCA to be able to put VMs onto on VLAN 3705. Luisa, do you think otherwise?

There are no ORCA VMs for VLAN 3705, only site VMs on VLAN3705 passing through the rack to get access to other GENI resources also on VLAN 3705.

[lnevers@bbn.com]

Sorry about the ticket storm! :-)

This is not an ExoGENI issue, it is experimenter confusion! There is a lot of information to keep straight to set up an experiment that allows me to have 2 meso-scale sites, the VMs in ExoGENI rack and some campus resources (all on OF VLAN 1750). There are 8 separate sliver requests to get this done.

Closing ticket.
