[Openstack] [openstack][nova][glance] Avoid Image Copying

In  a traditional model, i think it would do. But here we are trying to acheive following.
1. No copy from any source to ephimeral storage of hypervisor
2. Boot time less than a minute for 750 gb image
3. Image will be updated ever 5 minutes(close to cdp)
4. Image coming from zfs store

So typically we want to boot directly from a zfs clone, which needs file kind of an access.since that was blocked due to security reasons, we are thinking if we can some how restrict and build some kind of whitelisting mechanism to take file access..

Why isn't the ability to clone cinder volumes an adequate solution for
this? That capability already exists.
