xen and pae?
 

Hi all :jawa: :confused:
i'm new to linux, what is these kernels: Xen and Pae?
tank you all.

xen is for virtualisation, the ability to "run computers in your compter". PAE is for systems with loads of RAM, say 4GB+. Xen-pae is a virtualised kernel that supports systems with > 4GB. so if you run `free -m`, you'll see all of that RAM. You don't need xen if you are running a "typical" server, laptop or work station.

hi
well it's great. i have only 2gb of ram (no need to pae),
but in windows i'm usually use vmware.
is it Xen somethings like that? i've found VirtualBox, it's great.
how i can use xen?

I'd stick to what you know for now especially if you are new to GNU/Linux.

Xen "more-or-less" does the same thing as vmware, but in my opinion I can do much more with it because I have access to the source code. This means that I can remove the parts that I don't like or add things that I want. You can't do that with vmware cos you have no access to the source code.

Here is a presentation that I've come across that explains some of this virtualisation stuff.
