I don’t want to do periodic snapshots. I want to take snapshots on demand and when I do that I need to get rid of my oldest snapshot. VMPP doesn’t provide me an option for doing that.

This can be done through some interface and DB. You will need to record the snapshot and its date in DB and then depending on date you can destroy the oldest snap.

Also last_shutdown_time field doesn’t give me details about snapshot ,does it? Also is there a method for deleting the snapshot? Destroy method in VM class destroys a VM but not a snapshot I believe.

You can use xe vm-uninstall to completely remove the snapshot. I'll check about the last_shutdown_time.

Subject: Re: [Xen-API] Delete a snapshot

Hi Vijay,

You could look at vmpp ( VM Protection Policy ) to take periodic snapshots and delete the oldest one.

Another safe way would be to create a Parent-Child relation amongst the VM-Snapshot and compare the dates / timestamps.
Have you checked the "other-config (MRW): last_shutdown_time " ?

Hi – I am trying to figure out a way to delete a snapshot from a VM and could not find the right API to do that. I basically want to delete the most oldest snapshot of a VM. How do I do that?
I found the timetamp field of the VM class, but that is returning invalid timestamp for a timestamp for me for some reason. Any idea how to figure out the oldest snapshot and delete it?

Any help would be appreciated.
