OCI Classic provides an EC2 lookalike metadata service. * The UUID provided in DMI data is not the same as the meta-data provided instance-id, but has an equivalent lifespan. * We do need to support upgrade from an instance that cloud-init identified as OpenStack. * Bare metal instances use iSCSI root, virtual machine instances do not. * Both bare metal and virtual machine instances provide a chassis-asset-tag of OracleCloud.com.
