Steps for what? It's in /var/lib/lxc/{Container}/rootfs/

The warnings are perfectly normal and harmless. I ran into this with
recent versions of yum and researched it. It's because /proc is not
mounted in the container itself when the container is being created.
You can ignore them.

I've seen that on my Dell 610's but they haven't caused any real

Not sure what the deal is with that ATA error. That's a hard drive lost
interrupt problem. Looks to be on your CD Rom drive? Looks like it
