      Switch to "dynamic" creation of certain virtual nodes (jail/pcvm and · 4d5620c2
      Leigh B. Stoller authored
      vserver/pcplab). Rather then 10000s of fixed node entries in the DB,
      create node entries on the fly as needed (assign_wrapper), and then
      delete them when they are no longer used (nfree). When new nodes check
      in, no longer create all those nodes table entries (utils/newnode.in
      and tbsetup/plab/libplab.py.in).
      I've added a new library: db/Node.pm which is something I started a
      while back, and decided to commit, along with the support for creating
      and deleting virtual nodes. CreateVnodes() creates a new set of nodes,
      choosing non-conflicting names in the DB, and then immediately
      reserves them to the pid/eid specified. DeleteVnodes takes a list of
      vnodes and deletes them from nodes,reserved,etc. This library does a
      few other things which I am going to be playing with, so you might
      want to go read the comment at the top of the file. Feel free to speak
      up. CreateVnodes() is from called assign_wrapper when a node type has
      the "isdynamic" property. Otherwise does the existing avail/nalloc
      stuff. DeleteVnodes() is called from nfree when the node type has the
      isdynamic property.
      I've added a script (sql/delvnodes.pl) to run after updating the DB
      and software. All free pcvm and pcplab virtual nodes are deleted from
      the DB; reserved ones will get deleted whenever their experiment ends.
      I've noted all of this in doc/UPDATING, including setting the
      isdynamic property on pcvm in the node_types table.
      I've left tbsetup/plab/libplab.py.in to create a single pcplab node
      for the management sliver (still called -20). We can worry about this
      All this for modelnet?
