Update the Nova driver's rebuild() to account for changes in the instance image during rebuild. Currently, rebuild ignores user requests to rebuild with a new image, making it impossible to do image-based upgrades. This adds logic to the patcher to account for the preserve_ephemeral flag and updates rebuild() to use the patcher to re-patch all driver_info during rebuild. This also adds missing test coverage of the rebuild code. Change-Id: I6c8aacd36e0095d0590a1dc552730f2d52036225 Closes-bug: #1334905.
Ironic
Ironic is an Incubated OpenStack project which aims to provision bare metal machines instead of virtual machines, forked from the Nova Baremetal driver. It is best thought of as a bare metal hypervisor API and a set of plugins which interact with the bare metal hypervisors. By default, it will use PXE and IPMI in concert to provision and turn on/off machines, but Ironic also supports vendor-specific plugins which may implement additional functionality.
