I tried to create 3 partitions, one for the current OSX Mavericks, one for Lion and one for the installation dmg, but it seems that the Fusion drive doesn't allow me to create more than 2 partitions.

enter image description here

Therefore I can't burn a DVD, I don't have disc drive, I would like to know how can I install Lion on a partition on my mac, and keep using the main partition with Mavericks.
