The section in the xcat idataplex quick start that was referenced by chris meant xcat 2.8 disables selinux on the *management node*. If you look in http://svn.code.sf.net/p/xcat/code/xcat-core/branches/2.8/xCAT-server/sbin/xcatconfig around line 441, you'll see this section of code:
# Turn off selinux on RedHat
if (-f "/etc/redhat-release")
{
my $rc=xCAT::Utils->isSELINUX();
if ($rc != 0)
{
xCAT::MsgUtils->message('W', "SELINUX is not disabled,
disabling it now...");
# Disable selinux for running system
my $cmd = "echo 0 > /selinux/enforce";
my $outref = xCAT::Utils->runcmd("$cmd", 0);
if ($::RUNCMD_RC != 0)
{
xCAT::MsgUtils->message('E', "Failed to disable SELINUX.");
}
# Disable selinux through reboots
my $cmd = "sed -i
's/^SELINUX=.*\$/SELINUX=disabled/' /etc/selinux/config";
my $outref = xCAT::Utils->runcmd("$cmd", 0);
if ($::RUNCMD_RC != 0)
{
xCAT::MsgUtils->message('E', "Failed to disable SELINUX.");
}
}
}
So during xcat installation on the MN you should have seen the msg that it
was disabling it. Is it possible there is something different about about
disabling selinux on 6.4 versus 6.3 and below? Open a bug
(https://sourceforge.net/p/xcat/bugs/) and we'll investigate it.

I have to investigate. I thought we always in the past disabled SELinux
on the installed nodes, so this would not be new to 2.8.

Ah, but isn't that for the nodes it deploys? The section I'm
referring to is prior to installing xCAT on the management node itself
and the page says (perhaps incorrectly) that xCAT 2.8 should do the
disabling for you on installation.
But perhaps there's been a miscommunication somewhere that's resulted
in a misdocumented feature for the management node that should be for
the nodes it installs?
cheers!
