How do you go with big virtual disk's? I run a file server with a 2TB
virtual disk, but don't want a 2TB data log to back up every time I run it.
Same goes with a heap of VMs with 100Gb disks, I don't really want to take
up another 100gb of space every day I back up, that's why my current
solution is vProtect as I can do weekly full and daily incrementals but
always keen to see other implementations especially for large disks.

Indeed. A felt like there was need for a simple way to backup ovirt
vms.
Ansible may just be the answer. After some more testing of the playbook I
plan to publish a blog post/guide on the subject so others can use it.

Hi Lars, you might find this email thread interesting:

Jayme is trying to solve pretty much the same problem as you - although
he's using the Ansible approach instead of SDK. Feel free to join that
conversation. At this point it seems like he might have found a good
solution, but he needs to test it.

hi,
I tryed this with API 4.2 and 4.3.
purpose of the following script is, to export a given list of vm as OVA one
after another.
To reach that i need to monitor the job status and pause the script till
the actual export is done.
The script works fine, but not the restriction of the returned jobs to the
one spcificaly job i need to monitor.
Therefor the script pauses on *any* running job.
the working script:
#!/usr/bin/python
import logging
import time
import ovirtsdk4 as sdk
import ovirtsdk4.types as types
connection = sdk.Connection(
url='https://ovirtman12/ovirt-engine/api',
username='admin@internal',
password='***',
ca_file='/etc/pki/ovirt-engine/ca-ovirtman12.pem',
)
hosts_service = connection.system_service().hosts_service()
hosts = hosts_service.list()[0]
vms_service = connection.system_service().vms_service()
vms = vms_service.list(search='name=blxlic954')
for vm in vms:
# print("%s (%s)" % (vm.name, vm.id))
vm_service = vms_service.vm_service(vm.id)
start_time = (time.strftime('%Y%m%d_%H%M%S', time.localtime(int(time.time()))))
vm_service.export_to_path_on_host(
host=types.Host(id=hosts.id),
directory='/nfs_c3/export',
filename=('%s_backup_%s.ova' % (vm.name, start_time)),
wait=True,
)
# time.sleep(5)
jobs_service = connection.system_service().jobs_service()
jobs = jobs_service.list(search='')
for job in jobs:
print(job.id, job.description)
# job = jobs_service.job_service(job.id).get()
while job.status == types.JobStatus.STARTED:
time.sleep(10)
job = jobs_service.job_service(job.id).get()
print('job-status: %s' % (job.status))
connection.close()
The line
jobs = jobs_service.list(search='')
works fine as long as the search pattern is empty.
if i try to restrict the results returned like this:
jobs = jobs_service.list(search='description=*blxlic954*')
i get an error:
bad sql grammar [select * from (select * from job where ( job id in (select
distinct job.job id from job where ( ) )) order by start time asc) as
t1 offset (1 -1) limit 2147483647]; nested exception is
org.postgresql.util.psqlexception: error: syntax error at or near ")"
looks like the 'where' clause is not filled correctly.
Am i wrong with my syntax or ist that a bug?
Is there another way to get the correct job id/status?
