These are the instructions for creating an end-user VM from scratch.

VM Configuration

• Using VirtualBox:
  
  • 1 Core
  • 3G RAM
  • 500G System Disk (VDI, Dynamically Allocated)
  • Set network to "Attached to Bridged Adapter"

Base OS Install

• Centos 6.4 x86-64
• English language and keyboard
• hostname: localhost.localdomain (the default)
  
  • if it is localhost it should set it to the dhcp hostname provided.
• eth0:
  
  • Clear "Device MAC address"
  • Connect automatically
  • IPv4 Settings
    
    • Automatic (DHCP)
      
      
• set timezone to america/indiana/indianapolis, clock uses utc
• root password is 'changeme'
• partitioning:
  
  • custom layout
    
    • /dev/sda1:  500M ext4 mounted as /boot
    • /dev/sda2:  (remainder of disk) Physical volume
    • Volume Group:  vg_avalon
      
      • PVs: /dev/sda2
      • LV lv_swap 2G
      • LV lv_root (remainder of disk) ext4 mounted as /
• Desktop install
• Reboot / Firstboot
  
  • Leave all of the defaults, except...
  • Do Not create a new user
• Log in as root
  
  • do not check "do not show me this again" to the "you are running as root" dialog.  Just close it.
  • yum update
  • open these ports in the firewall:
    
    • tcp/22
    • tcp/80
    • tcp/1935
    • tcp/18080
  • clean up eth0 configuration in /etc/sysconfig/network-scripts/ifcfg-eth0:
    
    • remove UUID
    • remove any DHCP_CLIENT_ID
• OPTIONAL:
  
  • shut down the VM
  • at this point the vm is at "baseOS" and can be used as a cloning point

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1

Avalon Install

• OPTIONAL:
  
  • clone the baseOS image as puppet-YYMMDD
• Use the installation notes from Manual Puppet Install
  
  • When setting FACTER_* environment variables, set
    
    • FACTER_avalon_dropbox_password to "changeme"
    • FACTER_avalon_public_address to "localhost.localdomain"
• HACK: maintain permissions for dropbox
  

  • create script /usr/local/bin/fix_dropbox_permissions with this content:

    #!/bin/bash chown -R avalon:dropbox /var/avalon/dropbox find /var/avalon/dropbox -type f -exec chmod 664 "{}" ";" find /var/avalon/dropbox -type d -exec chmod 2775 "{}" ";"

    and set the mode to 755.

  • set the cronjob to run every minute by adding this line:

    * * * * * /usr/local/bin/fix_dropbox_permissions

Demo Content

• OPTIONAL:
  
  • clone the puppet image as democontent-YYMMDD
• Register the archivist1@example.com user in Avalon, and log in as that user.
  
  • this account is removed when the system is prepared for delivery.
• Create a 'Default Collection' collection with the archivist1@example.com user.

• Get the demo fixtures bundle

  cd /tmp wget http://www.avalonmediasystem.org/downloads/DemoFixturesBatch.tar.gz tar xvzf DemoFixturesBatch.tar.gz chown -R avalon:dropbox DemoFixturesBatch chmod -R g+w DemoFixturesBatch mv DemoFixturesBatch /var/avalon/dropbox

  Monitor progress in Matterhorn (at http://<whatever>:18080 using the default username/password) or within Avalon.

• Download the demo content thumbnails

  cd /tmp wget http://www.avalonmediasystem.org/downloads/DemoFixturesThumbnails.tar.gz tar -xzvf DemoFixturesThumbnails.tar.gz chown -R avalon:avalon DemoFixturesThumbnails mv DemoFixturesthumbnails /var/www/avalon/current/app/assets/images

• Modify /var/www/avalon/current/app/views/catalog/_home_text.html.erb and replace sample content with something like:

  <ul class="thumbnails"> <li class="span3"><h5>Featured Video</h5><a href="<%= media_object_path('avalon:1') %>" class="thumbnail" ><%= image_tag "DemoFixturesThumbnails/organClip.jpg", alt: "Featured Video" %></a></li> <li class="span3"><h5>Featured Video</h5><a href="<%= media_object_path('avalon:2') %>" class="thumbnail" ><%= image_tag "DemoFixturesThumbnails/lunchroomManners.jpg", alt: "Featured Video" %></a></li> <li class="span3"><h5>Featured Audio</h5><a href="<%= media_object_path('avalon:3') %>" class="thumbnail" ><%= image_tag "DemoFixturesThumbnails/mahler.jpg", alt: "Featured Audio" %></a></li> </ul>

  The values "avalon:1" to "avalon:3" should be changed to the appropriate container IDs

• Reload the avalon application by running

  touch /var/www/avalon/current/tmp/restart.txt

  and verify the changes are correct.

• Fix access permissions on all three items:
  
  • edit each item
    
    • click on the "Access Control" tab
    • click on the "Available to the general public" radio button
    • click Save
    • Click the 'Publish" button if it is available on the item view (Lunchroom Manners).

• Remove source data

  rm /tmp/DemoFixturesBatch.tar.gz rm -rf /var/avalon/dropbox/DemoFixturesBatch

VM Image Prep

• OPTIONAL:
  
  • clone the latest democontent image as dist-YYMMDD
• Install avalon-vm-2.0-1.noarch.rpm to install the firstboot changes and tools
  
  • Binary Package:  http://www.avalonmediasystem.org/downloads/avalon-vm-2.0-1.noarch.rpm
  • Source Package: http://www.avalonmediasystem.org/downloads/avalon-vm-2.0-1.src.rpm
• If IPv6 was disabled during install, re-enable it by removing the lines added to /etc/sysctl.conf during BaseOS.  If these lines are not removed, email will not work.
• Prepare the disk for compacting
  

  • clean up anything that's left over from the build process

    rm -rf /root/Downloads/* /var/avalon/dropbox/* /home/makerpm/rpmbuild /opt/staging /root/avalon-installer-flat /root/flat.tar.gz yum clean all swapoff /dev/mapper/vg_avalon-lv_swap; dd if=/dev/zero of=/dev/mapper/vg_avalon-lv_swap bs=1M; mkswap /dev/mapper/vg_avalon-lv_swap

  • deleted files still take up space on the disk image.  The disk image (as of 4/24/13) is roughly 12G in size, with 7.8G of actual data.  Write zeros to a file until the disk is full to clear out the sectors which are unallocated but had data at one point.  Since the .VDI image is sparsely allocated, the disk image size will actually grow less that 1G even though nearly 500G has been written.

    dd if=/dev/zero of=/tmp/foo bs=1M oflag=direct; rm /tmp/foo

• run /usr/share/avalon/dist-prep to prepare the machine for release
• clear the command line history  (history -cw)
• shutdown the VM
• Compact the disk image
  

  • On the host run:

    VBoxManage modifyhd avalon-vm-disk-YYMMDD.vdi --compact

• Export the appliance
  • Disable USB 2.0 in the VM to avoid a warning when users don't have the VirtualBox extensions loaded.

  • VM Settings:

    Name	Value
    Name	avalon-vm
    Product	Avalon Media System
    Product-URL	http://www.avalonmediasystem.org
    Version	R2

• copy the OVA to the distribution point
  • Make sure to set the avalon-vm.ova symlink to the current release
  • Set the permissions to 644 (they're 600 by default)
