Please post the full output of
   cat /proc/mdstat
   cat /etc/mdadm.conf
   mdadm -Evvs
   file -s /dev/sda
   file -s /dev/sda1
   file -s /dev/sdb
   file -s /dev/sdb1
   cat /etc/grub/grub.conf
(from inside the running VM, obviously).

I have to say I don't like the wiki article you quoted as a method of 
installation, but let's see if we can fix it before starting out doing 
it another way.

In addition, you probably ought to be testing on bare metal similar to 
your future production box.

Cheers,

John.
