+OpenStack uses healthcheck timers which run off wall-clock time rather then
+starting a timer and expring the timer, encoding the expiration in the message
+contents. In some cases, this timer interval can be on the order of 60
+seconds. For OpenStack to Operate correctly with these tight health-check
+timer intervals, the Kolla community highly recommends running the ntpd
+service on all deployment targets. To install, start, and enable ntp on
+CentOS execute the following:
+
+::
+
+ yum -y install ntp
+ chkconfig ntpd enable
+ service ntpd start

Libvirt is started by default on many operating systems. Please disable libvirt
on any machines that will be deployment targets. Only one copy of libvirt may
be running at a time.
