All your nodes need to have the correct time. You can specify an NTP 
server in the Packstack answer file or as a CLI option and then 
Packstack will configure your nodes to use that NTP server. If you don't 
specify an NTP server then Packstack doesn't handle NTP so you will have 
to do it yourself. Either way, make sure that all nodes always have the 
correct time.

You need to disable NetworkManager and enable network service. Before 
you run Packstack you will also need to setup the ifcfg-XXXX network 
interfaces on all nodes and activate them.
