> /dev/random is a PRNG, and predictable. You shouldn't use it for security applications but only for specific state/algorithm randomness. > /dev/urandom requires hardware noise/key events, etc. to generate its entropy. These become hard to find when your dealing with purely virtualized installations. You have it backwards. http://en.wikipedia.org/?title=/dev/random http://en.wikipedia.org/?title=/dev/random
