    On the xenserver we always keep the latest snapshot in primary as xenserver needs it to
create delta snapshots. If the snapshot is not present in xenserver, next snapshot would create
full snapshot rather than delta snapshot. Please refer to the bug related to that
    https://issues.apache.org/jira/browse/CLOUDSTACK-2630

>          Components: Storage Controller
>    Affects Versions: 4.8.0
>         Environment: Xen Server
>            Reporter: subhash yedugundla
>             Fix For: 4.8.1

> Issue Description
> ===============
> 1. Create an instance on the local storage on any host
> 2. Create a scheduled snapshot of the volume:
> 3. Wait until ACS created the snapshot. ACS is creating a snapshot on local storage and
is transferring this snapshot to secondary storage. But the latest snapshot on local storage
will stay there. This is as expected.
> 4. Migrate the instance to another XenServer host with ACS UI and Storage Live Migration
> 5. The Snapshot on the old host on local storage will not be cleaned up and is staying
on local storage. So local storage will fill up with unneeded snapshots.
