) .This extension exposes api to set and retrieve the disk_config values ( either 'MANUAL" or "AUTO' ) .As a user one wants to access the value of disk_config from inside of instance but currently there is no way to get the value of disk_config from inside
of instance.<br>
To get any metadata/userdata of the instance a config drive ( [[</span><span style="font-size:10.0pt;font-family:"Arial","sans-serif""><a href="http://docs.openstack.org/trunk/openstack-compute/admin/content/config-drive.html" target="_blank"><span style="font-size:9.0pt;color:#0033AA;text-decoration:none">http://docs.openstack.org/trunk/openstack-compute/admin/content/config-drive.html</span></a></span><span style="font-size:9.0pt;font-family:"Arial","sans-serif";color:#333333">]]
