Since I am new to fog, I need your assistance in understanding imaging part.

I have customized Ubuntu 16.04 desktop created in KVM. The name of image is ubuntu-16.04.img. I want to install this image to my other VMs using fog.

For testing, I copied this image file to /images folder as ubuntu-16.04 and created new image from console, but I am running into problem here. The size of disk on server is showing 0.

Now I am not sure if I am doing it correctly. If I am making mistakes, can somebody please guide me in process?

Is it also possible to use dm-crypt/LUKS for software encryption? If yes, can you tell me how to do it?

Thanks,
