Guillermo,
To create the VM, I followed Jonathan Marsden's instructions:
http://www.xc.org/jonathan/openacs/openacs4-rpm-based-install.html
It looks like it doesn't configure postgresql to restart on boot.
Type "/sbin/service postgresql start" to get it running.
Does anyone know how to get it to start on boot? The chkconfig command in the docs did not seem to work.
It's RH 7.1.
