      More work on image permissions; allow specification of pid/osname in · cfc9612a
      Leigh B Stoller authored
      NS files. Tweak permission check in Geni CM to also allow this,
      although at this time only global images from any project are allowed.
      The virt_nodes table has been changed to accommodate pid/osname
      syntax:
      
      	tb-set-node-os $nodeA somepid/someos
      
      Note: we are really exporting permission to use images, not entries in
      the os_info table (OSIDs) which is what the NS parser and protogeni CM
      are using. But in fact, an image is both an image descriptor and an OS
      descriptor linked together, so if you export an image or make it
      global, you are implicitly doing the same for the OS descriptor. As
      mentioned many times in the past, OSIDs suck.

      Initial support for loading Windows7 .wim images via WinPE/ImageX. · ac711ea5
      Mike Hibler authored
      1. Support for "one-shot" PXE booting ala the one-shot osid. Switches to
         pxelinux to boot WinPE and then switch back after done. Painful now
         because we have to HUP dhcpd everytime we change the PXE path, but we
         may be able to fix this in the future by going all-pxelinux-all-the-time.
      
      2. Added pxe_select, analogous to os_select, for changing the pxe_boot_path
         including the one time path.
      
      3. Added the WIMRELOAD state machine to shepherd a node through the process.
         Still has some rough edges and may need refining.

      Power "saving" additions from Barry Trent, who got them from Kevin · 03478fb9
      Leigh B Stoller authored
      Lahey.
      
      Power saving turns off nodes that have been sitting in PXEWAIT (and
      are thus free) for more then a set amount of time (see sitevar
      general/idlepower_idletime, which defaults to 3600 seconds).
      
      The driver script is tbsetup/idlepower.in and needs to be added to
      /etc/crontab at sites that want to do this. Even so, operation is
      enabled by the sitevar general/idlepower_enable. Each time it runs, it
      checks for nodes that need to be turned off, and then calls power.
      Note: This should be a daemon not a cron job.
      
      To be considered for power saving, you must add an attribute to the
      node_type_attributes table called 'idlepower_enable', set to 1.
      
      Locally, I hacked up stated and power to make the state transitions
      legal so that stated does not whine. I added POWEROFF as a valid
      transition from any state, to opmodes NORMAL, NORMALv1, and NORMALv2.
      Barry's original patch already had a state transition for PXEKERNEL.
      In power, I added code to look at the actual operation, and in the
      case of "on", do not send an event if the node is not in POWEROFF,
      since a user can foolishly say power on anytime, and the node is on
      nothing is every going to change, and the state transition would be
      wrong.
      
      node_reboot takes of powering nodes on, when they are in POWEROFF.
      
      Barry on copyright issues:
       "I'm not sure those rights are mine to grant! Remember that this code
       came originally from Kevin Lahey (kml@patheticgeek.net) and
       originated at DETER (although he's apparently not there anymore). I
       don't foresee a problem from our point of view (but I'll double
       check, of course). Shall I try to contact Kevin try to sort this mess
       out, or do you think it's better to coordinate from your end?"

      Add support for all node "tb-set-tarfiles". · a0d0c95e
      Kevin Atkinson authored
      "tb-set-tarfiles" is like "tb-set-node-tarfiles" except that it
      distributes the tarfile to all nodes rather than just one and that it
      uses frisbee to distribute the file.
      
      These changes involved 1) refactoring frisbee info from images table
      into a new table, frisbee_blobs, 2) a new experiment_blobs table, and
      3) a new tmcd command so the node knows how to get the files from the
      server.
      
      The changes where designed to be general purpose enough to eventually
      support:
        1) Distributing arbitrary files (not just tarfiles) to nodes
        2) Perform arbitrary actions on those files
        3) Use arbitrary methods to get the files
      
      As such the tmcd line is as follows:
        URL=* ACTION=*
      
      where URL is currently:
        frisbee.mcast://<ADDR>/<FILE>
      for example
        frisbee.mcast://234.16.184.192:18092/users/kevina/home-dir.tar.gz
      and when we get around to using a master Frisbee server it could be
        frisbee://*
      or it could be a file://, http://, etc.
      
      and ACTION is currently:
        unpack:<LOCATION>
      for example
        unpackt:/users
      with future syntax to be determined.

      Handle a common failure on the node reload path. · 4dc57d48
      Mike Hibler authored
      Under load, nodes that have just entered reloading and have just rebooted
      might fail to get bootinfo.  The default behavior in this case is for the
      node to boot from disk (dubious, but that is the topic for another day).
      This causes the node to fall off the RELOAD path, winding up in either
      TBFAILED or ISUP.  Worse, if the node makes it to ISUP, its reload state
      is cleared and even if the reload_daemon reboots the node, it will still
      not go through the reloading process.
      
      The result is a bunch of nodes left in reloading.  Now if a node makes an
      invalid transition to TBFAILED or ISUP while in the RELOAD state machine,
      it fires the new REBOOT trigger which does...well, you figure it out.
      Note that in the ISUP case, this trigger overrides the default that would
      otherwise clear the reload state--so reboot is sufficient to get the machine
      back on the RELOAD track.

      Changes for speeding up elabinelab server setup. · 6feda7d3
      Mike Hibler authored
      Boss/ops/fs: reboot them together after setup rather than serially.
      
      Nodes: leave them in PXEWAIT throughout the setup, until after boss has
      been rebooted.  At that point we send them the new bootinfo RESTART command
      telling pxeboot to re-DHCP and use the new info obtained (next-server) to
      contact a potentially new boss node.  This is a quick way to switch a node
      in PXEWAIT from talking to the outer boss to talking to the inner one.
      
      A significant number of rinky-dink changes were needed to do this, primarily
      adding a new state, PXELIMBO, where nodes can be sent to sit until they are
      restarted.  It turns out, just putting them in an existing state such as
      PXEWAKEUP or SHUTDOWN wouldn't work, as they tend to timeout or otherwise
      reboot.

      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.
