Hi John

I have no idea of what the error may be...
Did you check with md5 if the file you downloaded is corrupted 
(probably not, if the installation completed successfully)? You should 
get exactly this string:

$ md5sum lilydev-4.0-i386.hybrid.iso
9da792275907b44cd6b98f67b64a33f5

Did you enable PAE in Virtualbox, as explained in point 5 here?

If all above is correct, try:

1. checking the log file of virtualbox
2. running virtualbox from the command line and hopefully you'll get 
more useful information
