      Changes to support XEN shared nodes and guest snapshots. · 2489c09b
      Leigh B Stoller authored
      Snapshots are done a little differently then openvz of course, since
      there are potentially multiple disk partitions and a kernel. The basic
      operation is:
      
      1. Fire off reboot_prepare from boss. Changes to reboot_prepare result
         in the guest "halting" insted of rebooting.
      
      2. Fire off the create-image client script, which will take imagezips
         of all of the disks (except the swap partition), and grab a copy of
         the kernel. A new xm.conf file is written, and then the directory
         is first tar'ed and then we imagezip that bundle for upload.
      
      3. When booting a guest, we now look for guest images that are
         packaged in this way, although we still support the older method
         for backwards compatability. All of the disks are restored, and a
         new xm.conf created that points to the new kernel.

      Replace license symbols with {{{ }}}-enclosed license blocks. · 6df609a9
      Eric Eide authored
      This commit is intended to makes the license status of Emulab and
      ProtoGENI source files more clear.  It replaces license symbols like
      "EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
      blocks that contain actual license statements.
      
      This change was driven by the fact that today, most people acquire and
      track Emulab and ProtoGENI sources via git.
      
      Before the Emulab source code was kept in git, the Flux Research Group
      at the University of Utah would roll distributions by making tar
      files.  As part of that process, the Flux Group would replace the
      license symbols in the source files with actual license statements.
      
      When the Flux Group moved to git, people outside of the group started
      to see the source files with the "unexpanded" symbols.  This meant
      that people acquired source files without actual license statements in
      them.  All the relevant files had Utah *copyright* statements in them,
      but without the expanded *license* statements, the licensing status of
      the source files was unclear.
      
      This commit is intended to clear up that confusion.
      
      Most Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the Affero GNU General Public License, version 3
      (AGPLv3).
      
      Most Utah-copyrighted files related to ProtoGENI are distributed under
      the terms of the GENI Public License, which is a BSD-like open-source
      license.
      
      Some Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the GNU Lesser General Public License, version 2.1
      (LGPL).

      control network, so that we can use routable IPs.
      
      Create a swap volume for the guest. This addition is reflected in
      rc.frisbee but not the linux version; looks for a disk with a dos
      partition labeled as linux swap.
      
      Look in the node attributes for additonal disk specifications and
      create those disks (logical volumes). This is currently used in the
      XEN elabinelab to add more disks for inner boss and ops, and look
      like:
      
        $myboss add-attribute XEN_EXTRADISKS "disk1:10G,disk2:10G,disk3:10G"
        $myops  add-attribute XEN_EXTRADISKS "disk1:4G,disk2:10G"
      
      It is up to the guest to do something with these, we do not partition
      or label the volumes.

      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.

      Xen vnode fixes. · cadc2e6a
      Mike Hibler authored
      Fix some bitrot in the Linux code: fixup /etc/fstab to have an old-style
      LABEL=/ rather than a UUID.
      
      Don't allocate more than 768MB of memory to a FreeBSD 8 vnode as it panics
      otherwise.

      Lovely, lovely hacks for BSD based Xen vnodes. · e20c2034
      Mike Hibler authored
      In dhclient-exit-hooks we stash the vnode name in $BOOTDIR/vmname where
      libsetup would expect it.
      
      In libsetup.pm we set the event server to the physical host (based on
      node names!)
      
      In libvnode_xen.pm we reflect that these hacks are now done elsewhere!

      Revamp of Jon's libvnode_xen stuff. · 99c7c340
      Mike Hibler authored
      The model changed a bit after Jon did his version
      (with the introduction of dynamically created vnodes on shared nodes).
      
      This is still a work in progress.
