Merging the xen-hptool functionality into xl would be a good improvement.

It uses:
andrewcoop@andrewcoop:~$ ssh idol xen-hptool
xen-hptool: Xen CPU/memory hotplug tool
Usage: xen-hptool <command> [args]
  help                     display this help
  cpu-online    <cpuid>    online CPU <cpuid>
  cpu-offline   <cpuid>    offline CPU <cpuid>
  mem-online    <mfn>      online MEMORY <mfn>
  mem-offline   <mfn>      offline MEMORY <mfn>
  mem-status    <mfn>      query Memory status<mfn>
