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.
