Bug Description

If cinder is enabled the osapi_volume argument is removed from enabled_apis in nova.conf, but if neither cinder or n-vol is enabled it's still there. Currently this leads to:

commit 6e7e1c941a3ea9e2d30a6b59ccce2c5efa44b349

    Don't enable osapi_volume if n-vol not enabled.

    Enabling cinder removes osapi_volume from enabled_apis in nova.conf but
    if neither cinder or n-vol are enabled it should not be there. It seems
    that volume code is being removed from nova so osapi_volume should not
    be enabled by default.

    Fixes bug #1073701
