 #
 # Playbook to adjust Nova allocation ratios
 #
-# Versions tested: Newton, Ocata
+# Versions tested: Newton, Ocata, Pike
+#
+# Newton, Ocata apply changes to the Controllers as Pike applies changes to the Computes
 #
 # Examples:
-# ansible-playbook -i hosts browbeat/adjustment-nova-allocation.yml -e "cpu_allocation_ratio=24"
-# ansible-playbook -i hosts browbeat/adjustment-nova-allocation.yml -e "cpu_allocation_ratio=24 ram_allocation_ratio=10.0"
-# ansible-playbook -i hosts browbeat/adjustment-nova-allocation.yml -e "cpu_allocation_ratio=24 ram_allocation_ratio=10.0 disk_allocation_ratio=10.0"
+# ansible-playbook -i hosts browbeat/adjust-nova-allocation.yml -e "cpu_allocation_ratio=100.0"
+# ansible-playbook -i hosts browbeat/adjust-nova-allocation.yml -e "cpu_allocation_ratio=100.0 ram_allocation_ratio=100.0"
+# ansible-playbook -i hosts browbeat/adjust-nova-allocation.yml -e "cpu_allocation_ratio=100.0 ram_allocation_ratio=100.0 disk_allocation_ratio=100.0"
 #
 # In order for new settings to take affect, you need to restart the Nova services
 # by adding variable restart_nova=true into the extra vars.

 # * Note not setting a variable does not change that configuration item then. Setting no variables
 #   and running the playbook sets all configuration items to defaults (cpu/ram/disk - 16/1/1)
