I think VMDK subtypes are very relevant information and has to be indicated before a deployment. Just an example: if you try to deploy a streamOptimized or even some sparse formats directly to VMware ESXi they won't work, and troubleshooting for newbies can be complicated. I'm not very famliar with Glance yet. So may be some of my asumptions can sound stupid... I guess that one of the main purpose of Glance is to deal with Object Storage Services (Swift or S3 for example) because they are the best candidates to store virtual images. I think this is a 'necessary evil': such a big images must be stored somewhere. What I don't really get is how Glance is going to deal with all the different virtual images formats supported for the different hypervisors. I mean, who is going to convert from virtual image format X to the virtual image format needed by hypervisor Y? Is Glance responsible for this or the Compute Node? May be if you explain me a little bit how it will work I can be more helpful. I'm still with Austin and I will start to work on the Bexar branch very soon.
