[one-users] open-nebula front-end hardware requirements

It really depends on what transfer mechanism (ssh, nfs, or other)
you are going to use.  The OpenNebula "oned" and "sched" daemons
don't usse very much memory or cpu.  The load on my 8-node
cloud head node is 0.01 right now.

The load comes if you are going to have a centralized image repository
on the head node and transfer everything via ssh/scp to the VM hosts.
In that case a robust disk RAID array is more important than CPU.
