A while ago, this question was asked and answered (http://communities.vmware.com/message/1020415) for VIMA, but the answer no longer seems to work.
If you've assigned the wrong IP, or need to change the hostname, it would be great to restart the initial wizard.
It used to be that you could run:
sudo /usr/bin/system-config-network
But this no longer exists. Any idea what it is now?
