http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU In reading that How To, will using the GUI Configuration Tools create all the files need to run a "DomU". Will I have manual edit any configuration files?
Next question is the machine has 256MBs of ram and Dom0 uses about 225MBs of it. Is that a bit much? VmWare Server does not use that much ram. See #top Below....With out running the Xen Kernel it has no where near the ram usage as with the Xen one. Is that expected?

Yes, you can use virt-manager to do this.

dom0 takes the memory it can use, but if you create a domU, Xen will use "ballooning" to reduce the amount of memory allocated to dom0. You can set the minimum of dom0 memory in /etc/xen/xend-config.sxp by tweaking the dom0-min-mem option.
Be aware that the hypervisor also takes a chunk of memory, so you may want to add more memory to get a useful setup.
Take care, Daniel
