      First crack at limiting the node types assigned to new images. · fff92262
      Mike Hibler authored
      Currently we declare the valid types for an image to be those that are of
      class "pc" and for which we have at least one node in the testbed.
      
      With this change, when an image is created as a snapshot from an existing
      node, we look at the partition info for the existing image to further
      restrict the types that the derived image will work on.
      
      This will prevent images derived from old images like RHL90 or FBSD410
      from getting newer node types such as pc745d as a valid type.
      
      One problem with the current solution is that, we don't know til the form
      is submitted once, what node you are snapshot'ing, so the first time a
      user submits the form, it is almost certain to come back with an error.
      
      Further, they have no choice but to uncheck the offending types.  If part
      of their customization was to add support for a new node type...too bad,
      ya' can't add it!  There are numerous ways to fix this, all of which exceed
      my Friday afternoon mad hacking skilz.

      Minor nits. The most important: when selecting eligible node types from the · c112aeb4

      DB, only select those for which a node of role 'testnode' exist.  This will
      eliminate the pc1500, where we only have a couple of tipservers of that type.

      Another round of widearea node hacking for CMU. These changes add · 99346dc0
      Leigh B. Stoller authored
      widearea reloading support.
      
      * New slot in the images table to store an access key which remote
        sites must provide in order to download an image (via https).
      
      * tmcd returns a different kind of ADDRESS field from doloadinfo.
        Instead of the multicast stuff, return a URL that points to boss'
        web server. The URL is of the form:
      
         https://www.myemulab.net/spewimage.php?imageid=10013&access_key=abcdef
      
        which as you can see is fully specified; the client does not need
        to know anything else.
      
      * New webpage and backend scripts appropriately called "spewimage"
        which also includes support for the http HEAD request (from wget) to
        avoid downloading images that are already on the node. I just
        learned about this HEAD request stuff today ... but otherwise these
        operate as expected, spewing the image if the access key is provided.
      
      * Changes to rc.frisbee to deal with remote loading. In addition to
        URL support, I also added support for simple paths, the intent being
        that we will probably distribute images offline (say, at night) so
        that when a node reboots it doesn't actually have to wait 60 minutes
        for an image to download. I have not added any server side support
        for this yet though. Maybe later this week.
      
      * Other bits and pieces and fixes to make this work.
