      Some very basic infrastructure for generalized tools was added. · 639758e6
      Dan Gebhardt authored
      Some parts very "hacky", lots of XXX / TODOs.
      BARELY tested!!!! Don't use on the production system yet.
      Need to verify that things didn't break, especially with the automanager,
      the bgmon.pl "outage detection stuff", etc...
      
      See code's todos and also the file
      flexlab-canonicalization-misc-notes.txe
      
      At this point:
       - mangerclient & automanagerclient did not change.
       - The manager, when a probe request is received, looks at the DB table
         "tool_spec" to retrieve the proper wrapperpath, formal parameter list, etc..
       - The manager assembles a message and sends it out to the appropriate
         path probers, which operate on the request as they have been
         (no major internal changes to the path probers).
       - The path probers call the toolwrapper to run the tests
       - The toolwrappers return a canonical result for that type of metric.
       - The path probers send the result and the actual parameters used by the
         tool to the data collector.
       - The data collector uses the toolname and actual parameters to get an
         idx number. This idx is stored in the "measured_by" field of this
         measurement's entry in the "pair_data" table.

      - latency measurements under 2 second intervals now operate in "continuous"
        mode: a single "ping" process runs per destination, versus the "normal"
        approach of forking a new fping process for each measurement instance.
      
      - Note, that I found a bug which is not fixed in this checkin: if a latency
        test is running in continuous mode and another latency measurement request
        is received with a shorter interval, the "continuous" ping process is not
        re-initialized with the new, shorter interval.

      First cut at porting our jail setup to linux vservers. Most of the · 0910c65c
      Leigh B. Stoller authored
      changes are on the client side where I took mkjail and retargeted it
      to vservers (called it mkvserver.pl, clever eh?) in the linux
      directory. The real time sync was understanding how vservers work, how
      they boot how they die, how they handle signals, etc. Very interesting
      and very bizarre. Anyway, this first cut is done with the version 2.2
      vserver code which does not virtualize the network stack or even the
      loopback device, so I pretty much ignored the experimental network and
      the host routine stuff. So, in your NS file you can now do this:
      
      	set ns [new Simulator]
      	set v0 [$ns node]
      	set v1 [$ns node]
      
      	tb-set-hardware $v0 pcvm
      	tb-set-hardware $v1 pcvm
      	tb-set-node-os $v0 FC-VSERVER
      	tb-set-node-os $v1 FC-VSERVER
      
      As you can see, I am using the osid to indicate jails vs
      vservers. There are some small changes in assign_wrapper that use the
      nextosid of the osid to map to the actual osid to install on the
      hosting node. If you try to collocate a jail and a vserver assign will
      refuse, cause we use features and desires for the osids. Sweet.
      
      Oh, the ssh button in the web interface does not work yet cause the page
      assumes that local virtnodes can bind to port 22 in each vserver, but
      that will not work yet.
