Description of problem:
If ovirt-engine is installed on machine with less than 4GB, after successful installation a message appears:

 * There is less than 4 GB available free memory on the Host.
It is  recommended to have at least 4 GB available memory to run the RHEV Manager.

In the second line - I don't want to run RHEV Manager but oVirt.

Also the first line seems a little bit misleading since I have no Host set up yet, I would go with something like "..memory on this machine" or so.

Version-Release number of selected component (if applicable):
ovirt-engine-3.0.0_0001-1.3.fc16.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install ovirt-engine on machine with less than 4GB RAM
