      Add tracking of control net mac addresses in the node_history. · bb66f52e
      Leigh B Stoller authored
      For InstaGeni, need to record and be able to search for history by
      control net mac address. We now record this in the node_history table,
      with corresponding change to the ShowNodeHistory web page.
      
      The backend changes required are that we 1) actually generate a mac
      address for VMs and stick it into the interfaces record, 2) return
      that mac from tmcd in the jailconfig, and 3) have the openvz library
      create the control net interface using that mac.
      
      On the openvz image, needed to switch to using a control network
      bridge for all interfaces (not just routable ones) so that traffic
      leaves the node with the correct mac.

      managed.
      
      * Try much harder to prevent broken VMs from getting left behind.
      
      * Try even harder to prevent left of state (devices, volumes, etc)
        from getting left behind once a VM breaks.
      
      * Store all the assorted bits of state we create in a file so that it
        it can be cleaned up later.
      
      * Watch for "stale" VMs that got left behind, using the UUID, which is
        regenerated each time an experiment is swapped in. Since we now
        store all the state that was associated with the stale VM, we can
        actually tear it down later. To do this by hand:
      
         node> sudo /usr/local/etc/emulab/mkvnode.pl -c pcvmXXX-YYY
      
      * Lots of changes to signal handling to avoid a common problem case;
        trying to reboot or halt a VM that is still setting up.

      Add the ability to load images on virtnodes. For now, we just overload · c6c57bc9

      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.
