An error occurring when calling "xl cpupool-cpu-remove" might leave the system in a state where a cpu is neither completely free nor in a cpupool. This can easily be repaired by adding the cpu via "xl cpupool-cpu-add" to the cpupool where it was removed from before. Print a message telling this the user in case of an error.
