Last night I managed to finally figure out how to bridge a VM to the local network so I can tie everything together in a flat topology. I ended up having to create a new interface on the Host01 Network management page of Cockpit, and after that, tit worked the first time. I was not sure it did, but I logged into a VM and saw the additional interface with my LAN IP retrieved via DHCP.
With that out of the way, I will spin up the remainder VMs and get their MAC Addresses so I can assign fixed IPs to them and make them easily accessible via DNS. I like the DHCP option since it gives me flexibility and a cross check to make sure everything is working right from the start.
Then, I will spin up a standalone Hadoop server on the workstation, and add the VMs as Datanodes with Spark clients. I need to plan the data directory location and change the storage sizes of the VMs as well. Then there is monitoring.
