+    The nova/neutron/ceilometer host parameter is now explicitly set to the
+    same value that is written to /etc/hosts. On a correctly configured
+    deployment they should be already be identical. However if the hostname
+    or domainname is altered (e.g via DHCP) then the hostname is unlikely to
+    resolve to the correct IP address for live-migraiton.
