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