 ==== Building Ganeti ====
+I'll select Ganeti to start with as it appears the simplest to setup.  I've no need for services like fail-over or migration.  Just the ability to rapidly many tiny nodes from a template.  It also appears that Ganeti clusters can be embedded with Openstack later.
+On hold, these Xen tools are very nice, no need for Ganeti up front (virt-manager, virt-clone, virsh).

+To come.
