Part 2 of 6: blueprint general-bare-metal-provisioning-framework In baremetal provisioning, one nova-compute manages multiple bare-metal machines. A bare-metal machine does not run openstack at all. Previously, bare-metal provisioning used text files to store information of bare-metal machines. In this patch, a MySQL database is used to store the information. We target only MySQL database. The DB is designed to support PXE/non-PXE booting methods, heterogeneous hypervisor types, and architectures. Using a MySQL database makes maintenance and upgrades easier than using text files. The DB for bare-metal machines is implemented as a separate DB from the main Nova DB. The DB can be on any machines/places. The location of the DB and its server needs to be specified as a flag in the nova.conf file (as in the case of glance). There are a couple of reasons for this approach. First, the information needed for bare-metal machines is different from that for non-bare-metal machines. With a separate database for bare-metal machines, the database can be customized without affecting the main Nova DB. Second, fault tolerance can be embedded in nova-compute. Since one nova-compute manages multiple bare-metal machines, fault tolerance of a nova-compute node is very important. With a separate DB for bare-metal machines, fault-tolerance can be achieved independently from the main Nova DB. Replication of the bare-metal DB and implementation of fault-tolerance are not part of this patch. The implementation models nova and its DB as much as possible. The bare-metal driver must be upgraded to use this DB.
