kali is a VERY specialized Operating System and is basically used for one propose
and installing a VM on it is NOT one of those uses
it is based on Debian so you "can" but and this is a big one
it really is used for pen testing and NOT running other OS's
then add to it that Kali is NOT recommended for NEW to linux users
you really DO need a masters in CS and network security to use the tools in it
