 Patching the Host Cloud
 =======================
 
-.. note: Patching the host cloud is now optional. On clouds where the Neutron
-         port-security extension is enabled, it is now possible to run without
-         patching. However, the PXE boot patch may provide a better user
-         experience with OVB, so patching may still be desirable.
