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. � N)� namedtuple)�Optional�Tuple)�dmi)�log)�net�sources�util)� NetworkConfig)�cmdline� ephemeral�get_interfaces_by_mac�is_netfail_master)�UrlError�readurl�configure_secondary_nicsFzOracleCloud.comz&http://169.254.169.254/opc/v{version}/z{path}/i(# � Authorizationz Bearer Oracle� OpcMetadataz version instance_data vnics_datac @ s e Zd ZdZdefdd�ZdS )� KlibcOracleNetworkConfigSourcez�Override super class to lower the applicability conditions.
