[Openstack] Large image snapshots

[David Kranz]

I am a bit ignorant about image formats and such. The size of the Ubuntu 
precise cloud image at 
http://uec-images.ubuntu.com/precise/current/precise-server-cloudimg-amd64-disk1.img 
is about 221Mb. If I boot that image with flavor m1.tiny and use 
image-create I get an image that is 2Gb. If I do the same with flavor 
m1.large the resulting image is 10Gb.  Is there a way to create 
snapshots that don't result in huge images?
