      Added support for rspec version 2 to ptopgen. · bb76cd3b
      Jonathon Duerig authored
      Note that command line arguments for ptopgen are tweaked slightly so that after '-g' for GENI, you must enter a version number. Changed invocation in GeniCM. Also, tweaked rspec definitions to make it conform to reality on the ground inside of our system as it gets implemented.

      Changes to support the SPP nodes. My approach was a little odd. · fd015646
      Leigh B. Stoller authored
      What I did was create node table entries for the three SPP nodes.
      These are designated as local, shared nodes, reserved to a holding
      experiment. This allowed me to use all of the existing shared node
      pool support, albeit with a couple of tweaks in libvtop that I will
      not bother to mention since they are hideous (another thing I need to
      fix).
      
      The virtual nodes that are created on the spp nodes are figments; they
      will never be setup, booted or torn down. They exist simply as place
      holders in the DB, in order hold the reserved bandwidth on the network
      interfaces. In other words, you can create as many of these imaginary
      spp nodes (in different slices if you like) as there are interfaces on
      the spp node. Or you can create a single spp imaginary node with all
      of the interfaces. You get the idea; its the reserved bandwidth that
      drives the allocation.
      
      There are also some minor spp specific changes in vnode_setup.in to
      avoid trying to generalize things. I will return to this later as
      needed.

      Add the ability to load images on virtnodes. For now, we just overload · c6c57bc9
      David Johnson authored
      the tb-set-node-os command with a second optional argument; if that is
      present, the first arg is the child OS and the second is the parent OS.
      We add some new features in ptopgen (OS-parentOSname-childOSname) based
      off a new table that maps which child OSes can run on which parents, and
      the right desires get added to match.  We setup the reloads in os_setup
      along with the parents.  Also needed a new opmode, RELOAD-PCVM, to handle
      all this.
      
      For now, users only have to specify that their images can run on pcvms, a
      special hack for which type the images can run on.  This makes sense in
      general since there is no point conditionalizing childOS loading on
      hardware type at the moment, but rather on parentOS.  Hopefully this stuff
      wiill mostly work on shared nodes too, although we'll have to be more
      aggressive on the client side garbage collecting old frisbee'd images for
      long-lived shared hosts.
      
      I only made these changes in libvtop, so assign_wrapper folks are left in
      the dark.
      
      Currently, the client side supports frisbee.  Only in openvz for now, and
      this probably breaks libvnode_xen.pm.  Also in here are some openvz
      improvements, like ability to sniff out which network is the public
      control net, and which is the fake virtual control net.

      Changes for shared nodes. · cb912d49
      Leigh B. Stoller authored
      * 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.
