With the release of Ubuntu 12.04 I thought I'd try my luck with a private home cloud, I've been reading everything I could find but I've got some questions. I'm thinking of a pretty simple setup of 1 controller and 3 nodes. I know I need 2 NICs on each computer but I can't understand how to connect them all together. I've understood that you connect one NIC from each computer(nodes and controller) on a switch which only connects these together and the second NIC on each computer with a second switch that is also connected on the internet via router. Is that right?
I know my descriptions are somewhat lacking and at times quite confusing so I've made a schematic of how I've understood the process: http://biglle.com/node.jpg
And one final question, does the controller also act as a DHCP server for the whole network(there are other computers connected in the same network)?
If there is any info missing please let me know and I'll update this post. Thanks a lot.
EDIT: I had something like the setup shown in this tutorial in mind: https://help.ubuntu.com/community/UbuntuCloudInfrastructure
