I would add more RAM and swap but more importantly if you want to use
it as a full VM you would be better off attaching the ISO to the
virtual CD drive, boot the VM using the CD drive as the boot drive.
When sugar runs launch the terminal Activity and run the command
'liveinst' which will do a proper install to hard disk of the live
image. This then will have a proper install and not one with an
overlay. A overlay of 200 Mb will be the cause of the ext4 crash.
