Possibly in: rhel-guest-image but I get a nil result in the .spec file, and a qcow2 image, which may contain such, when I look [ Reading ~/rpmbuild/SOURCES/rhel-guest-image/guest-image-ovf-creator.py from that SRPM is sort of a disturbing mish mash of python code, and instance data. Why no driver file to specify the instance, and so to isolate code from data? ] I too am interested in where that file comes from. Pointer appreciated, as we support in this space I see later reply by Richard: > I have no idea where it comes from, and I doubt it is up to > date. > > $ grep RHEV-App libguestfs.spec > Source7: RHEV-Application_Provisioning_Tool_46267.exe and I'm with him! I have no idea either, but am interested in the answer I think you MAY be referring to the capability of the type provided via 'cloud-init' (present as early as: 0.7.1 -- in via a rebase at RHEL 6.5 [0], which asserts it is at cloud-init-0.7.2) to mount and source a ConfigDrive (actually, a Config ISO-9660 ISO disk image) [1] [2]. There is a MSFT analog as well, and VMWare seems to run similar updates from time to time Red Hat support for such in its enterprise product seems to be explicitly adding ConfigDrive (also written as two words in some places) as of late 2013 [3], bugfix [4] to work properly under a 2.6 kernel Richard had posted as to a tool for making such without the ened for root rights a while back titled: Creating a cloud-init config disk for non-cloud boots [5] but the utility of article is broader than the title implies (thanks, Richard) -- Russ herrold End Notes: ========== I do not see 'rhel-apt' as a sub-target in the spec file for rhel-guest-image either: [herrold@centos-6 rhel-guest-image]$ rpmno.sh \ rhel-guest-image-6.5-20131115.0.el6.src.rpm rhel-guest-image.spec guest-image-ovf-creator.py rhel-guest-image-6-6.5-20131115.0-1.qcow2 [herrold@centos-6 rhel-guest-image]$ grep "rhel-apt" rhel-guest-image.spec [herrold@centos-6 rhel-guest-image]$ Please excuse the negative number footnote, but I've been composing this all morning and a couple hours into the afternoon, as well organizing my knowledge into a form I can refer to in the future as to CloudDrive's [-1] https://github.com/cloudbase/cloudbase-init [0] https://bugzilla.redhat.com/show_bug.cgi?id=968246 [1] http://cloudinit.readthedocs.org/en/latest/topics/datasources.html#config...
