The guide on http://docs.openstack.org/developer/heat/getting_started/on_ubuntu.html (http://docs.openstack.org/developer/h...) suggests that pre-built images can be downloaded from http://fedorapeople.org/groups/heat/prebuilt-jeos-images/ (http://fedorapeople.org/groups/heat/p...) , and there several versions for each OS, such as F17-x86_64-cfntools-pkg.qcow2, F17-x86_64-cfntools.qcow2 and F17-x86_64-gold.qcow2. What are the differences among them? Some templates supplied by Heat use F17-x86_64-cfntools.qcow2, F17-x86_64-gold.qcow2, but it seems none of them uses the one with -pkg.

Hi the images are built using the process documented in: http://docs.openstack.org/developer/h...

Using the oz templates in: https://github.com/openstack/heat-tem...

The "gold" templates do not contain the additional heat-cfntools scripts, which are required for some heat functionality, however we no longer maintain the "gold" tdls, so these images should probably be removed

Likewise the "-pkg" images look to be old images which should probably be removed - I'm not sure exactly what differences there are from the non-pkg images, but we won't be supporting their usage.

If you want to check the image contents, you can use libguestfs, then diff the results for two images: virt-ls -Rl -a F17-x86_64-cfntools.qcow2 /

I suggest using the F17-x86_64-cfntools.qcow2 image. I'll follow up and get the old images removed soon, and hopefully get some newer images for F18 and newer Ubuntu version uploaded.
