Are these Linux distros useable as virtual hosts?

Q. Are there pre-built packages for, or guides to build, programs like Virtualbox on Damn Small Linux, Puppy Linux, or Tiny Core Linux? Or is there any low resource OS's that I haven't listed that would be better suited for the task of being a virtual host? I am wanting to try it out on my current pc before I build one specifically for virtualization.

Also, is it possible to stream a virtual OS from a server so that all the processing is done there and not on the client PC? ( kind of how certain rental companies stream a game to your computer, allowing you to play it, even if your computer doesn't meet the requirements.)

A. I presume you have a decent server so it can run big apps, so try Puppy, it's up to date and capable, unlike those others which might be missing things. Or try Bodhi, which is Ubuntu with a E17 desktop. Fast, and you've got all the Ubuntu repositories.

What is the lighest(resources"Ram,Cpu" not OS size) linux distro while still having great performance?
Q. I am aiming towards Lubuntu because of being light on resources and fast computing and has a nice interface.
I am open for suggestions about light(resources) linux distro but not in favor of losing performance since performance is my top priority.

A. Lubuntu is good choice. There are even lighter distro like Siltaz, Tiny Core, Puppy, etc You don't need something like that unless you have a system 9 years old or more. I got a regular Ubuntu 10.10 to work nice on a P4 with 512 MB of ram after uninstalling a bunch of unneeded stuff like Compiz and bluetooth.

What's the advantage of running Linux in your RAM?
Q. The way I understood it, a tiny Linux distro like Puppy or Tiny Core still needs to boot from SOMEWHERE e.g. a CD, pen drive, hdd before it loads into RAM, right? And it'll also need a medium to save the changes you've made to the system on.
So why not use LESS RAM and have it boot from an internal medium like a hdd or flash where anything else can be saved as well?

A. there are many use cases for running in ram or a "live" distro. your hdd or os went kaput and you want to try to mount it to save any data. you have no need to save data such as a linux-based firewall appliance like pfsense. you want to test a distro first before committing and installing. you want to run memtest. as you can see running in ram means you're not modifying the existing system's os.
