Vmplayer-virtual machine which is with high ease of use

I firstly installed vmplayer in March or April.I used vmware player on windows at that time.However,I used it installed Ubuntu,Redhat,Gentoo and Suse in my XP.I learned much from the first experience with it.But the vmx file of vmplayer is too large,for example,a gentoo occupied 8G space at that time.That is terrible enough.However,it is so easy to run other OS that we seldom need any knowledge of installing OS on our desktop.It is a goood choice for newbies.
