Proxmox Change Node IP

Whether you need to change a proxmox node's ip or change them all the steps are the same. In my particular case, I have two networks, a fast network and a faster network, so I wanted to switch all my proxmox hosts to use the ip address associated with the faster network interface ... to do that

1. For each node in the cluster, change the /etc/hosts file and make sure each hosts new ip address is associated with its name.

2. For each host, go ahead and run the following command

   /etc/init.d/cman restart
