[Planetlab-devel] Re: PlanetLab updates

[Adams, Robert]

Will the old and new PLC's report which nodes are in which version? That
is, will the www.planet-lab show nodes disappearing and www2.planet-lab
show nodes appearing in sites.xml until all nodes are moved over. I
think I can make my slice manager talk to both APIs to add and remove
slices, but asking www.planet-lab which nodes a slice is on and not
getting any information about the slices allocated in www2.planetlab
might be a bit confusing. And visa-versa.

Could you be a little clearer on what information will be available on
each system? Part way through the conversion, what will each of the PLCs
report? How will we know which nodes are converted? Are you going to
publish the list of which nodes are being converted in the next time
period?

Inquiring minds want to know.

Yes, for now, you'll have to keep track of which nodes are being run by
the old 
NM, and which are being run by the new NM. Create your slices on both
APIs. But 
get tickets for nodes run by the old NM (those not in the "Rollout"
group) from 
the old PLC, and get tickets for nodes being run by the new NM (those in
the 
"Rollout" group) from the new PLC.

The new call is GetSliceTicket(), you should get back a GPG encrypted
blob that 
you can decrypt and verify with the PlanetLab public key:

It's fairly human readable XML.
