Some more details on my system.
I am running CentOS 6.5. To install libvirt and LXC, I performed the following command:
yum install libvirt libvirt-client python-virtinst
I have turned selinux to DISABLED.
When you say disabled, do you actually mean you booted with selinux=0 or do you just mean you set it to permissive. In RHEL-6 there was a bug that could break LXC if you boot with selinux=0. Running with selinux enabled, but in permissive mode should work just fine though.

Hello,
I am having difficulty getting any sort of LXC container running. I am trying to use the following tutorial to run the hello world example:

Here are the results of my running the tutorial:

As you can see, I am getting an error. How do I go about diagnosing this error? This is a fresh install so the only thing I have been using this machine for is for LXC/libvirt testing.
You can try looking at /var/log/libvirt/lxc/$GUEST.log if that has insufficient info, then you can do service libvirtd stop edit /etc/libvirt/lxc.conf and set log_with_libvirtd=1 LIBVIRT_LOG_FILTERS=1:lxc LIBVIRT_LOG_OUTPUTS=1:stderr /usr/sbin/libvirt and then start the guest - the guest log file should then have much more info in it.
