Yes you can do that, but if you have plenty of RAM you might find it 
nicer to install the OS you'll run most on the base hardware, then 
install the free vmware server and install all the others as vmware 
guests so you can run one or more without having to reboot or shut down 
the base system.  The guest images normally live in ordinary files on 
the host so they are easy to manage and they can nfs-mount a common 
share from the host or other system fo access to common space.
