Added a '-1' option which can be used to get the rspec of a single node. Note that this doesn't attempt to optimize away any database lookups.

have that information in the widearea_nodeinfo table.

invalid XML.  We previously used a workaround in GeniSES.pm to keep
the demo alive.

find out how much bandwidth is currently reserved, so that
we can modify the bw on the physical interfaces appropriately, for
shared-nodes.

genimode.

I also wrote code to use the bandwidth slot of the vinterfaces table,
but moments after I wrote it I realized that the vinterfaces table has
benn cleaned by the mapper (RemovePhysicalState()) by this point, so
that will not work.

I do not have a viable solution yet.

shared. This cuts down on the rspec size for the demo; huge
otherwise.

Another temp hack; strip out interfaces that are not expt/ctrl to
prevent clutter and breakage in the interface list.

Added a bogus "(null)" interface to all switches to mollify assign. Still need to really solve this problem in a backwards compatible way.

from the main site; only nodes with reserved_pid set.

	if ($sharing_mode{$name}) {
	    print "  <exclusive>false</exclusive>\n";

	else {
	    print "  <exclusive>true</exclusive>\n";

packing to favor nodes that already have vnodes on them. This can also
come from the node_attributes table.

Then I disabled these changes cause it was causing me problems; the
shared nodes were not getting picked. Needs more thought.

CM URNs for links are now shown rather than UUIDs. Fixed bug in the 'available' tag which showed all local nodes as unavailable in rspecs. Fixed selection criteria so that all nodes are shown in an rspec rather than just the available ones.

Fixed to accomodate Tarun's tweaks to the schema which changed a few thing from elements to attributes and used interface_ref.

ptopgen now produces output which conforms to the rspec advertisement schema. It produces URNs rather than UUIDs.

* New option -h to turn on shared nodes; set by the mapper wrapper
  when it sees that an experiment wants to use shared nodes.

* When using shared nodes, look for physical nodes that are reserved,
  but have their sharing mode set. The node must also be up.

* Shared hosts nodes get the feature pcshared:1.0 in the ptop
  file. libvtop adds the corresponding desire.

* On the shared hosts, do not spit all the OSIDs, but just the one it
  is actually running. This allows the user to indicate what kind of
  shared node they want via the osid. libvtop adds that as a desire.
  Crude but effective.

* Use the interface_state table to get the remaining bandwidth on the
  interfaces for shared hosts, so that assign does not oversubscribe
  links.

* Some initial code to look at the load averages on shared nodes, to
  guide the packing. Not actually operation yet.

  At the moment packing is still controlled by the collocate factor
  from the experiment (NS file). Eventually we want to use the load
  averages above, or other feature/desire mechanisms to control
  packing.

<available> is now based on reality. interface node_uuids are also real. TODO: link_uuid, virtualization_type, (null) interface name.

ptopgen now generates a file which validates under the new rspec schema. ptop/ptopxml are identical. Some of the rspec output is still placeholder.

Special case for interconnects to make interface names source and dest rather than source:source/source_if and dest:dest_if

Finally checked in a refactoring of ptopgen's output code. This includes making rspecs mor rspec-y rather than just a slight variation of the ptop xml format.

node_attribute with key='protogeni_exclude'. Primitive, but since
there is a web interface and a backend script, its easy for remote
sites to use.

discover resources call.

handle local nodes -- to assign_wrapper and ptopgen, they're pretty
much the same.  If the "dedicated_widearea" node_type_attribute is
set for nodes of class pcRemote, we treat remote nodes like locals.
I stuck with using a node_type_attribute for this, but it makes fast
queries ugly.  I believe node_type_attributes are better than adding
yet another bit to the node_types table, but others may feel
differently.

multiple interfaces. The multiple interfaces issue is going to take
some thought and work to get right.

should not count against the global capacity limits.

attribute in the types table to cap the number of allowed virtual
nodes on each physnode (by type). We have to look in the reserved
table to see how many already allocated on each physnode, and adjust
the counts accordingly. Doing it here (via assign_wrapper) is not
atomic and so it could fail to catch an over subscription, but on a
lightly used testbed this will not be a problem in practice.
