The free Xen tools only show you the total memory being used by the
guest -- equivalent to the amount of RAM installed in the (virtual)
machine. They don't tell you how much memory is being used by
processes, in swap or in disk buffers. That is my eventual aim with
virt-free (part of the virt-mem toolset).
I have no idea about XenSource's commercial tools.
VMWare offer something similar but you have to install an agent inside

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
