[Users] Help on oVirt basic question

Hi Team, I am very new to the Ovirt. I am trying to install the ovirt-engine into one of my vm with the below spec. 1. 2GB Mem 2. 2 CPU 3. 1 NIC 4. 20GB storage 5. Centos 5.5 32bit I am following the http://wiki.gentoo.org/wiki/OVirt#Installing_oVirt_Engine_Core installation documentation. I am tryingto meet all the software dependencies throught the source tarball. I installed the maven, postgresql and jboss-as through tar ball. But, when i am trying to compile the webadmin and user portal using the "mvn -e -DskipTests=true clean install -Pgwt-admin,gwt-user" command it fails at the time of web-admin level. As per my under standings the ovir-engine is a java based jboss applicaiton it would not be an issue with the os version. Please help me to understand. Regards, Arumon
