LiveOS image
Below are instructions for preparing a VirtualBox disk image from a SoaS iso image file. The process parallels the compressed LiveOS image used on Live CD and Live USB installations.
- (Taken from Dave Bauer's posting at http://schools.sugarlabs.org/mod/forum/discuss.php?d=27.)
- Updated 16 August 2010 with VirtualBox 3.2.8 and 32-bit Fedora.
(Note: The SoaS .iso distribution also contains an installer for full, uncompressed, hard disc images of Fedora with the Sugar graphical interface. See Uncompressed, hard disc image below for instructions.)
Installing SoaS .iso image
- Create a new VM, choose a name, such as Mirabelle
- Choose Linux for the Operating System and Version Fedora (use 64 bit, if available)
- Choose Base Memory Size: 256 MB to match an XO-1, 512 or 1024 MB to match an XO-1.5
- Create a new virtual hard disk image with dynamically expanding storage of 2 GB
- Finish.
- Download the lastest SoaS, http://spins.fedoraproject.org/soas/#downloads, for Fedora 13.
- Mount the SoaS .iso image file as a CD-ROM in the newly created VM.
- Change the Network Attached to: Bridged Adapter (This allows for networking with the host computer.)
- Start the VM
- Enter an account name and startup Sugar.
- Open Terminal.
su -
parted
mklabel msdos
- This makes a partition table.
mkpart primary ext2 0 2048
- You will receive this message:
Warning: The resulting partition is not properly aligned for best performance.
Ignore/Cancel? - Enter (I)gnore
- You will receive this message:
toggle 1 boot
quit
mke2fs /dev/sda1
/LiveOS/livecd-iso-to-disk --overlay-size-mb 1024 --home-size-mb 200 --delete-home --unencrypted-home /dev/sr0 /dev/sda1
(for earlier versions of SoaS- Blueberry - use /media/soas-2-blueberry/LiveOS/livecd-iso-to-disk
Strawberry - use /mnt/live/LiveOS/livecd-iso-to-disk)
- Blueberry - use /media/soas-2-blueberry/LiveOS/livecd-iso-to-disk
- the --overlay-size-mb NNN and --home-size-mb NNN options creates space for persistence of changes on the disk; otherwise, a liveOS disk is read-only. See LiveOS image.
The following optional parameters seem to be incompatible with soas-1-strawberry and soas-2-blueberry released versions. (The script completes successfully, but the virtual machine startup process has trouble finding the home directory and fails to complete.)- the --home-size-mb NNN option creates space for file storage in the /home/liveuser folder. (In the case where you you want to update the LiveOS image while keeping the user files, skip the new disk creation and parted steps, leave out the --home-size-mb NNN option at this step, and continue on.)
- the --unencrypted-home option prevents password protection and encryption on the /home/liveuser folder. This releaves the overhead on the compressed SquashFS, and should be more robust to file system failures (outside of security).
- the --delete-home option is used to avoid an error message while requesting both a new home (with --home-size-mb) and a persistent home (with --unencrypted-home). (You wouldn't use this option for the LiveOS upgrade case.)

Installing VirtualBox Guest Additions
The VirtualBox Guest Additions requires installing DKMS and compiling virtual device drivers for the Linux kernel.
- Unmount CD/DVD in VirtualBox settings, select 'Empty' for the CD/DVD device under 'Attributes'
- Start the virtual machine
- Open Terminal
su -
- Determine the kernel version,
uname -a
Linux localhost.localdomain 2.6.33.3-85.fc13.i686 #1 SMP Thu May 6 18:44:12 UTC 2010 i686 i686 i386 GNU/Linux
- For SoaS-Mirabelle, the kernel is Linux-2.6.33.3-85.fc13, so specific kernel-headers and kernel-devel are needed:
yum install kernel-headers-2.6.33.3-85.fc13 kernel-devel-2.6.33.3-85.fc13 dkms gcc
- (Other dependencies will be called into the installation.)

Configure Screen
If you want to match the 16 bpp XO screen and a particular display size, you may
- Edit /etc/X11/xorg.conf to match the following section:
- 832x624 - matches default XO display proportions
- 1200x900 - XO reflective resolution
# VirtualBox generated configuration file # based on /etc/X11/xorg.conf. Section "Monitor" Identifier "Monitor[0]" ModelName "VirtualBox Virtual Output" VendorName "Sun Microsystems Inc" EndSection Section "Device" BoardName "VirtualBox Graphics" Driver "vboxvideo" Identifier "Device[0]" VendorName "Sun Microsystems Inc" EndSection Section "Screen" Identifier "Screen[0]" Device "Device[0]" Monitor "Monitor[0]" DefaultDepth 16 SubSection "Display" Depth 16 Modes "832x624" "1200x900" "1024x768" "800x600" EndSubSection EndSection
Clear user data
Finally,
- Open Terminal
- Terminal
- rm -rf ~/.sugar (if distributing image)
- su -
- shutdown -h now
- Now you can share the VDI file.
Backup discs
It would be wise to maintain a clone of your virtual disk image to restart if the working copy is damaged:
- From host command line (Windows cmd, or Linux terminal) See VirtualBox Help section 8.14.
- VBoxManage clonehd <uuid>|<filename> <outputfile> [-format VDI|VMDK|VHD|RAW|<other>] [-remember]
- Reclone any virtual hard disks you would like to archive.
SSH connections
To enable SSH communications, we need to permit no passwords (to match the default Sugar configuration) in the ssh daemon configuration:
- in Terminal,
- su -
- vi /etc/ssh/sshd_config
- [add] PermitEmptyPasswords yes
- :wq <Enter>
- service sshd restart
One may also supply a password for the root user:
- su -
- passwd
- Changing password for user root.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
- Changing password for user root.
