xl and xm compute the amount of memory used by VMs differently, in
particular xl returns the current amount of memory used by the VM, as
reported by the hypervisor.

What Xen version are you using? Could you please post the xl and the xm
config files of one of the VMs that show up differently?

If you are creating the VMs using xm and then executing "xl list", you
should know that this is not a supported configuration: either you use
xm or xl, you shouldn't mix them.
