You are missing an auto eth0
So the line
 auto lo
should now be
 auto lo eth0

--- Man page: http://man.he.net/man5/interfaces
Lines  beginning with the word "auto" are used to identify the physical
       interfaces to be brought up when ifup is run with the -a option.  (This
       option  is  used by the system boot scripts.)  Physical interface names
       should follow the word "auto" on the same line.  There can be  multiple
       "auto"  stanzas.   ifup  brings  the  named  interfaces up in the order
       listed.
