> If an ISO is attached to a running VM, and you delete that ISO via CloudStack, the ISO file is deleted from secondary storage. However, it is left attached to the running VM, and it cannot be detached while the VM is running. The exception given in the log is pasted below (full snippet attached). It appears that CloudStack is not even trying to detach it (no tasks show up on vSphere). 
> Shutting down the VM and detaching the ISO works fine, but this is an inconvenience at the least and should be handled better. For example, ISO deletion could fail if it is attached to any VM, ISOs could be automatically detached from VMs before being deleted, or deleted ISOs could be detachable from running VMs.
