Description RHOS Integration 2013-12-12 18:36:07 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/efficient-vm-boot-from-volume.

Description:

So far, the image backend storage is swift or swift-alike object-based storage. It takes a very long time to start a new VM, since glance needs to copy the image to the node, where this VM is launched. This can be improved by reading the image from the volume. In addition, the speed of lauching a VM can be accelerated by some techniques like copy-on-write, multipath read, etc. This one may overlap with Efficient Volumes From Images https://blueprints.launchpad.net/cinder/+spec/effecient-volumes-from-images. Not sure how much similar it is.
