Hi,
At this moment, the Keepalived plugin will install Keepalived software packages in all cluster's nodes and will create a suggested configuration that you can customize by yourself.
In the roadmap for this year we have the addition of a new FWCloud section that will allow Keepalived setup by means of the FWCloud web user interface.
Indeed we are already preparing it together with other new features for easily setup by means of FWClou-UI other firewall related software packages like HA Proxy, DHCP, etc.
