-----------------------------------------------
This review has been pending for a while. Nitin can you review this
> ISOs can be deleted while still attached to a running VM, and they

> Key: CLOUDSTACK-357
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-357
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: ISO
> Affects Versions: pre-4.0.0
> Reporter: deepti dohare
> Assignee: deepti dohare
> Priority: Minor
> Fix For: 4.1.0

>
> 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.
