it would be great to allow in deltacloud for disk format selection (thin/preallocated) when cloning from a template (launching instances) in rhev. the api seems to allow for it: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Virtualization/3.0/html/REST_API_Guide/chap-REST_API_Guide-VMs.html#sect-REST_API_Guide-VMs-Clone-Disk provide such a feature from the conductor web ui doesn't seem very useful to me as this is not a feature available from all the cloud providers nor setting it in the deployable file seems useful, for the same reason would it make sense to have some default in aeolus-configure/nodes/rhevm_configure ?
