I've pretty much built my own cloud here at Gorilla Nation using xCAT for baremetal and VM deployments.
I've written my own scheduler to allocate baremetal boxes for VMs based on my criteria. And I've written my own rebalancer to dynamically detect changing loads and move around VMs. These scripts are just little perl scripts that anyone can write for themselves.
