I think this tool is little bit better than others. I really appreciate features like sharing assigned disk-space like folder or other disk. It's not hard to install virtualbox into solaris.
I have installed SXDE 1/08 79b. It was same like in the VMware I had to use Command line installation (not Grahpical ) Graphical installer has still some issues and can not be used. Really good way to try SXDE or maybe the best 
.
