attribute than Jon's client was sending it in.  Let's agree on the name
and see if things work any better.

and ignore remote (i.e. mismatched URN) nodes, just as was done with UUIDs.

1. Allow use of the shared nodes via the "exclusive" tag in the rspec.

2. Switch to using the mapper in GetTicket() and in RedeemTicket() as
   per this email I sent:

* GetTicket(): New rspec comes in and I build a virtual topology as I
 parse the rspec. Basically, virt_nodes and virt_lans table entries,
 which are stored into the DB. The rspec can include wildcards or
 specific nodes; I use the "fixed" slot of the virt_nodes table. Note
 that I am not yet handling fixed ifaces. Nice thing about this is
 that all of the show exp tools work.

 I run the (new) mapper on it in "solution" mode. This does two
 things; wildcards are mapped, and 2) it verifies that the rspec is
 mappable on the local hardware. Solution mode does not actually
 change the DB, but rather it spits out an XML file that I parse
 (note, we eventually will pass the rspec through, but I am not ready
 for that yet). I then allocate the nodes to the holding area, update
 the rspec, create a ticket, and return it.

* RedeemTicket(): I run the new mapper again, only this time in real
 mode with -update. This is basically a redo of the run above since
 all the nodes are reserved already, but the DB is actually filled
 out this time. I then create the slivers and such.

 The other difference is that instead of creating the vlans by hand,
 I can now run snmpit -t to do the work for me. Ditto for tear down
 with snmpit -r.

 Another bonus is that I can add (missing) IP addressess during the
 initial rspec parse, and the nodes now boot and have their
 interfaces configured. Virtual interfaces too, including the ones
 inside of virtual nodes.

* All of the above works with shared nodes too:

"<rspec xmlns=\"http://protogeni.net/resources/rspec/0.1\"> " +\
" <node virtual_id=\"geni1\" "+\
"       virtualization_type=\"emulab-vnode\" " +\
"       virtualization_subtype=\"emulab-openvz\" " +\
"       exclusive=\"0\"> " +\
"   <interface virtual_id=\"virt0\"/> " +\
" </node>" +\
" <node virtual_id=\"geni2\" "+\
"       virtualization_type=\"emulab-vnode\" " +\
"       virtualization_subtype=\"emulab-openvz\" " +\
"       exclusive=\"0\"> " +\
"   <interface virtual_id=\"virt0\"/> " +\
" </node>" +\
" <link virtual_id=\"link0\"> " +\
"  <interface_ref " +\
"            virtual_interface_id=\"virt0\" " +\
"            virtual_node_id=\"geni1\" " +\
"            /> " +\
"  <interface_ref " +\
"            virtual_interface_id=\"virt0\" " +\
"            virtual_node_id=\"geni2\" " +\
"            /> " +\
" </link> " +\
"</rspec>"

The shared nodes boot, and you can ping on the experimental networks.

Caveats:

* UpdateTicket and UpdateSliver need work as per the mail I sent the
 other day about the state of the sliver between the ticket and the
 sliver operations.

* Collocation specifications are ignored since we do not have any way
 to specify this to assign when wildcards are used. Rob, I am
 wondering if assign has any tricks we can take advantage of.

* Still need to commit all the snmpit changes and get that hooked into
 the CM.

to ticket when there were no links in the rspec. 3) Print the rspec
out only when there is an error redeeming it, to reduce the amount of
email. 4) Fix check in updatesliver that looks for existing links; was
tearing them down cause the test was wrong.

support. Can even create multiple jailed nodes on the same physical
node. Sorry, no sharing of physical nodes yet (between slices).
Also no link support yet; coming later.

The syntax is an extension of the current hack syntax:

        " <node uuid=\"" + node_uuid + "\" " +\
        "       nickname=\"geni1\" "+\
        "       phys_nickname=\"geni1\" "+\
        "       virtualization_type=\"emulab-vnode\" " +\
        "       virtualization_subtype=\"emulab-jail\"> " +\
        " </node>"

This only works on sites that already can do jails.

its really a hugely stripped down Emulab boss install, using a very
short version of install/boss-install to get a few things into place.

I refactored a few things in both the protogeni code and the Emulab
code, and whacked a bunch of makefiles and configure stuff. The result
is that we only need to install about 10-12 files from the Emulab
code, plus the protogeni code. Quite manageable, if you don't mind
that it requires FreeBSD 6.X ... Still, I think it satisfies the
requirement that we have a packaged clearinghouse that can be run
standalone from a running Emulab site.
