If you are seeing poor performance in your virtual appliance environment, it is possible that the linux machine hosting your system has low entropy which is preventing processes from functioning as normal. 

If this is happening it is likely that rngd is turned off in the environment. 
1. If the machine doesn't have rngd running, please check the following: chkconfig --list | grep "rngd"

2. if on any machine, the output contains 3:off that means the rngd service was disabled

3. please run the following to enable the service: chkconfig rngd on 3
then run: sudo service rngd start

This will restart the rngd service, providing the needed entropy for the environment.
