Re: [Folsom] How VM is connected to Swift storage

You can use swift as backend to store the vm images (through glance). 
When a vm instance is created you can select these vm images as a source. 
Note that the image will be copied to local storage on the compute node when it is started so it is really just an image store, you can not directly run the image from swift.

Yes, the applications needs to be modified.
