<br>
I have an ISO image in Glance which contains some data, and I want to copy data to running instance. I find maybe the only way is first creating a volume from this image and then attach volume to the instance.<br>
<br>
I think it 's more or less not convenient. Can ISO image in Glance be attach to running instance directly?<br>
