I want to install Alfresco based in an OpenVZ VM based on the following 
recipe.  Do you think that will be sufficient if I allocate 1GB RAM to 
the OpenVZ VM?

Extract:

  4) Tune jvm memory settings. This is based on recommendations in the 
Alfresco Installer Guide pdf. Settings are tuned for a 768MB VM, which I 
think it should be the minimum memory for this app, which is memory 
heavy. I'm also setting the MySQL Hibernate Dialect as a jvm param.
