Hi,
I have 1 problem when using the Python SDK to make backups of virtual machine
images, after updating to Ovirt 4.5.
Before the update and with Ovirt 4.4 and Centos 8 everything worked.
Scenario:
Ovirt-engine - installed standalone, centos 9 Stream
Host -> Centos 9 Strem - ISO used was ovirt-node-ng-installer-lastest-el0.iso
Storage -> Iscsi
Ovirt-backup -> Vm runnnig on host with centos 8 Stream with
python3-ovirt-engine-sdk4 installed
Versions:
Version 4.5.6-1.el9
To reproduce the error, do the following:
1 -> Create a snapshot via interface GUI
2 -> Run this script to find my snaphot id
```
#!/bin/python
import sys
import printf
import ovirtsdk4 as sdk
import time
import configparser
import re
cfg = configparser.ConfigParser()
cfg.readfp(open("/opt/VirtBKP/default.conf"))
url=cfg.get('ovirt-engine', 'api_url')
user=cfg.get('ovirt-engine', 'api_user')
password=cfg.get('ovirt-engine', 'api_password')
ca_file=cfg.get('ovirt-engine', 'api_ca_file')
connection = None
try:
connection = sdk.Connection(url,user,password,ca_file)
# printf.OK("Connection to oVIrt API success %s" % url)
except Exception as ex:
print(ex)
printf.ERROR("Connection to oVirt API has failed")
vm_service = connection.service("vms")
system_service = connection.system_service()
vms_service = system_service.vms_service()
vms = vm_service.list()
for vm in vms:
vm_service = vms_service.vm_service(vm.id)
snaps_service = vm_service.snapshots_service()
snaps_map = {
snap.id: snap.description
for snap in snaps_service.list()
}
for snap_id, snap_description in snaps_map.items():
snap_service = snaps_service.snapshot_service(snap_id)
print("VM: "+vm.name+": "+snap_description+" "+snap_id)
# Close the connection to the server:
connection.close()
```
When i run the script i have the result of VM name + snap ID, so connection
with api is OK.
```
[root@ovirt-backup-lab VirtBKP]# ./list_machines_with_snapshots_all
VM: ovirt-backup: Active VM d9631ff9-3a67-49af-b6ae-ed4d164c38ee
VM: ovirt-backup: clean 07478a39-a1e8-4d42-bdf9-aa3464ee85a2
VM: testes: Active VM 46f6ea97-b182-496a-89db-278ca8bcc952
VM: testes: testes123 729d64cb-c939-400c-b7f7-8e675c37a882
```
3- The problem occurs when I try to attach the snapshot to the VM
I run the script below thats run perfect on previous ovirt version 4.4 and
centos 8

This is scenario on my LAB Test, in production i have 4 hosts, 3 on Centos 8
and 1 on Centos 9 Ovirt node image, and if my ovirt-backup machine running on
host with centos 9 Ovirt Node i have the same error that mentioned above, but
if i migrate my ovirt-backup to another host with Centos 8 do not have this
problem.
Any idea what could cause this problem?
Sorry if my English isn't understandable
Thanks
Luís Figueiredo
