Comment:

 After more testing and some feedback from the GeoNetwork team, these are
 the new findings:
 1. GeoNetwork works fine when booting iso on real hardware (tested on my
 1GB RAM netbook)
 2. The service starts fine under a VM with 1GB RAM but then freezes the
 system when Firefox tries to show the main page. This issue seems to be VM
 specific. Perhaps there is a memory overhead due to low quality graphics
 card?
 3. GeoNetwork team suggested to check the Java memory settings and define
 512 MB, which was already set in the setting file.
 4. When I do "sudo service tomcat6 stop" before starting GeoNetwork's
 Jetty, everything works fine.

 So my conclusion is that default tomcat + GN jetty on 1GB RAM bring down
 the system due to lack of swap space. On the other hand, other Jetty
 instances require less memory and work fine along with default tomcat.

 Thoughts? Perhaps we should document this somewhere in the docs? I would
 suggest NOT to change minimum RAM requirements, it would reflect bad on
 OSGeoLive requesting more than 1GB RAM in my opinion, especially when our
 base OS requires 256MB.
