Duplicate the old nova-bm logic of setting the default ephemeral device to /dev/sda1 (first partition on the disk) when an ephemeral partition is being used. This is a short-term solution to fix the majority of cases that depend on this value being present in the instance metadata (e.g., cloud-init). Longer term, we should consider using something like udev by-label names (/dev/disk/by-label/NNN) or similar. Closes-Bug: #1324286 Change-Id: Ia85f0fd0bfa5cca0320db0e8c7f1e0e2b61b4ef6
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.
