Hi!

You can attach a Cinder volume to a running instance...

To make a Cinder volume looks like a ISO, I think you can do the following
step at your "cinder-volume" node:

dd if=/my/iso/file.iso of=/dev/cinder-volumes/LOGICAL_VOLUME_OF_CINDER

Then, attach it to your instance...

I'm not sure if it will work but, it worth trying it...

Please, keep in mind that the above "dd" command will wipe out all data at
your cinder-volume logical volume "LOGICAL_VOLUME_OF_CINDER"!

Also, you can format (mkfs.ext4) your cinder-volume locally at its node,
mount it, copy the ISO into it, umount and attach it to your instance...

Best,
Thiago
