I remember running VMs in VMs when I was younger and wondered how far I could go before my computer would implode. Infinite recursion is amazing. Let me rephrase that; infinity is amazing.
After three to four iterations (cannot remember precisely) I couldn't split up my computer its capacities any further to qualify for any decent OS its specifications which could run another VM. Please note that this was years ago, I suggest you should try it!
Unless you want to waste a lot of time installing the nested OS's, like I did, I suggest using pre-installed images you can throw right in.
