Oracle has since created a Metalink note related to this The FMW Configuration Wizard Is Very Slow On Linux Virtual Environments. The Startup Of WLS Servers Is Also Very Slow. [ID 1344974.1]

Solution 1 1) Download and install the following rpm: rng-utils-2.0-1.14.1.fc6.x86_64.rpm . Contact your vendor for download details. 2) Startup the random generator as follows: rngd -r /dev/urandom -o /dev/random -t 1

By default there seems to be a dependency on /dev/random on Linux which blocks until enough randomness is generated. Virtual servers with no mouse and keyboard attached can block significantly. In the command above input is taken from the unblocking /dev/urandom so the wait for randomness does not become an application bottleneck.
