Add 2nd Partition as VM image

Hi there,

i need some help.
i like to do something like the Parallels option which uses the Bootcamp Partition as a VM with an OSX Partition.

what i have :

Macbook Air
OSX 10.9 on Partition 1
OSX Yosemite on Partition 2

i want to access Yosemite on Partition 2 from 10.9 on Partition 1 via VM ( virtualbox , vmware , parallels ... equal) and have the option to boot directly into the Yosemite on Partition 2.


thanks for help and ideas
