[ovirt-users] Setup new enviroment

Hello all, I was just wondering what your opinions would be in setting up a new oVirt enviroment. I have 4 old servers, 3 with 64 Gigs of ram and 2 tera's of disk space an one with 32 Gigs of ram and 1,2 Gb. Each has 2 hexcore cpu's. Each server has at least 2 nic's. I would like to use each server in a seperate cluster with there own local storage as this would all only be used as a test enviroment but still would like to manage them from one interface. Deploy new vm's from templates etc. Can I still use the all in one installation for engine and node ? Or can I install the engine on a seperate host, physical or virtual. What would be a good way to use the network ? Any advice would be greatly appriciated. Thanks in advance.
