hi and welcome.
A Security-Enhanced Linux Primer
Security-Enhanced Linux (SELinux) was developed by the U.S. National Security
Agency to provide a level of mandatory access control. It goes beyond the
discretionary access control associated with file permission and ACLs. In essence,
SELinux limits the damage if there is a security breach. For example, if the system
account associated with an FTP service is compromised, SELinux makes it more
difficult to use that account to compromise other services.

you might want to do at lease some research please
ubuntu dose NOT use it
Red Hat- RHEL6.3,Fedora, and CentOS 6.3 use the SELinux ENHANCED kernel

it is not a virtual environment you run a operating system in

it IS THE CORE of a operating system -- the Kernel --

Hello new member.

"I'm using a p4 machine and I want run ubuntu in it, can you help me as to get it done?
I have 1Gb ram in my machine."

That may be OK if you don't do too much. Ubuntu may have to be changed for maybe lubuntu or xubuntu or a different distro. Your old box may or may not seem fast enough with ubuntu. That has nothing to do however with SElinux. Many distro's have the ability to add in or enable easily SElinux.

CentOS 6.3 ( 32 bit) and ScientificLinux 6.3
both USE the SELinux enhanced kernel
and they both run fine on a OLD p4 box with 1 gig ram

I have SL 6.3 running just fine on a computer built in 2000 ( bought in early 2001 )
1 gig ram ( upgraded from the 256 meg it had)
a p4
and a antique Nvidia Gforce 2 card

As John said, SEL is a Fedora/CentOS thing, unless you want the trouble of installing it yourself. Similar is Aparmour, which comes with Ubuntu and its derivatives and also with OpenSUSE. Sometimes SEL can be too much of a good thing: Samsung say their printers won't run unless you switch it off and that's certainly true for me. Aparmour is less difficult.

Your computer is similar to the one I'm using, and I had to use some fancy tricks to get Ubuntu to boot: it doesn't care for older computers. If you haven't installed yet, I'd suggest Linux Mint (the Mate version), which will be fine.
