Instructions for preparing a VirtualBox disk image from a SoaS iso image file.
- (Taken from Dave Bauer's posting at http://schools.sugarlabs.org/mod/forum/discuss.php?d=27.)
- Updated 09 June 2010 with VirtualBox 3.2.4 and 32-bit Fedora.
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 200 --home-size-mb 200 --delete-home --unencrypted-home /dev/live /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.)

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 in the ssh daemon configuration:
- in Terminal,
- su -
- vi /etc/ssh/sshd_config
- [add] PermitEmptyPasswords yes
- :wq <Enter>
- service sshd restart
