Many thanks for the above script. I ran it on Ovirt manager. It worked. It
gave me the ID of my CentOS_71 VM that I want to backup.

I rewrote the script in this way and ran it.


#!/usr/bin/python

from ovirtsdk.api import API
from ovirtsdk.xml import params

# Connect to the server:
api = API(
    url="https://engine.example.com/ovirt-engine/api",
    username="admin at internal",
    password="******",
    ca_file="/etc/pki/ovirt-

> engine/ca.pem",
>     debug=False
> )
>
> # Find the VM:
> vm = api.vms.get(name="myvm")
>
> # Print the id:
> print(vm.get_id())
>

*vm.snapshots.add(          params.Snapshot(description="My
snapshot")         )*

No error was given. I have no idea whether snapshot wad added or NOT by the
above script.

I can't display it.

*How to display it?  *

Then, *How to backup the VM with this snaphot? *

Then, finally* how to delete this snapshot? *to delete the snapshot,

I tried with below command. the did NOT worked.



*vm.snapshots.delete() *or
  *vm.snapshots.detach(*

 or
  *vm.snapshots.remove(*

I think I am have completed about 50% of this backup process. If you can
write down the  above steps, It would be very grateful.


I searched a whole lot. But , I still can't do it.

These are the links I came across.

Hmm,


*How to list the sanphot? *

*how to backup the VM with snapshot? *

*finally , how to remove this snapshot? *


Then. I think it will be OVER. Yesterday, I tried a lot.  but, NO success.

Hope to hear from you.
