We were discussing memory limits of the free (as in beer) closed source citrix xensource product- limits are added to the free product in order to encourage people to upgrade to the more expensive products.
These limits don't exist in the open-source xen product, which is what the centos/Xen stuff is based on.

I've personally run CentOS x86_64 5.1 boxes with north of 16G ram- there is nothing I am aware of that would stop you from putting as much ram as you want in a particular DomU.
You will be needing PAE, but that is default for CentOS i386/xen, so it should Just Work. make sure you install the libc6-xen package (should be installed as a dependency.) The usual PAE limits apply.
I'm typing this message in emacs running on a DomU hosted on an i386/ PAE box with 6G ram running CentOS5.1/xen.
Hi Luke,
Thanks for the confirmation; this is what I had understood but some of the prior discussion scared me. :)
