Hi

When create an image which is raw (.img) format, I have an option named Format, If I select disk format as qcow2, it will convert my raw image as qcow2? if not, what is utility of disk format field? I select --Create Image-- in Horizon, select my raw image file, select qcow2 in --Format-- section, then I use image shod [Image ID], it show me disk format of image is qcow2, I wanna know that means my raw source image convert to Qcow2? I also select --Format-- of my raw image as VMDK and it created. converted? I can use vmdk or AMI as image file, when using KVM as hypervisor?!

Thanks
