Better way to do it is to look for /proc/user_beancounters. If it exists then it's a distro with OpenVZ kernel installation. In it there is a info about different parameters of the container (if you look into it inside the container) or containers (if checked from the HN). Container 0: is the HN, so if you have it listed in the file then you run outside of the container.
