| you need to install xenpae kernel.. ordinary 32-bit kernel can only address only 4GB memory

| In debian, xen kernel used to support PAE..
post the result of "yum list | grep -i xen" and "yum list | grep -i pae"

| I was wrong
http://www.centos.org/modules/newbb/...topic_id=12690
and 5.2 xen should also support PAE. So, it looks like you have a faulty RAM in your server. You need to get it checked by your NOC guys.
