What happened?

Update Default MachineCIDR from 10.x to 192.168.0.0/16 network.

#See the troubleshooting documentation (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md) for ideas about what information to collect.

#For example, 

# If the installer fails to create resources (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md#installer-fails-to-create-resources), attach the relevant portions of your `.openshift_install.log.`
# If the installer fails to bootstrap the cluster (https://github.com/openshift/installer/blob/master/docs/user/troubleshootingbootstrap.md), attach the bootstrap log bundle.
# If the installer fails to complete installation after bootstrapping completes (https://github.com/openshift/installer/blob/master/docs/user/troubleshooting.md#installer-fails-to-initialize-the-cluster), attach the must-gather log bundle using `oc adm must-gather`

# Always at least include the `.openshift_install.log`
