Hello,
I am used to create new vm with ovirt_vm module.
Now, I want that the disk of each new created vm to be with the incremental statement.
I tried so:
disks: - id: "{{result.disk.id <http://result.disk.id>}}" bootable: True interface: virtio_scsi backup: incremental
but it seems that the backup item is not implemented.
How to attach a disk with the incremental statement?
Unlike bootable, disk interface and such settings that are per relation between a disk and a vm, the 'backup' (method) setting is a property of the disk itself. If the disk was created with incremental backup enabled, it would remain with incremental backup enabled when attached to a vm
The exact workflow is:
* The disk is created with incremental backup enabled * The disk is attached to a vm(incremental backup is ok at this step) * the vm is exported as a template * *The disk of the new vm created from the template doesn't have the incremental backup enabled!*
Sounds like the imported disk of the template is not set with incremental backup, what version of ovirt do you use?
As part of the fix for https://bugzilla.redhat.com/show_bug.cgi?id=2081556, which was merged to 4.5.1, we started writing the incremental-backup property to OVAs (I assume you refer to export-to-OVA since you wrote that you export a VM as a template) I don't export vm as ova, I make a template from a vm or a snapshot. - if you use an older version (than 4.5.1), this could explain it. Otherwise, please provide the output of:
select * from base_disks where disk_id in (select device_id from vm_device where vm_id in (select vm_guid from vm_static where vm_name='<template-name>')); engine=# select * from base_disks where disk_id in (select device_id from vm_device where vm_id in (select vm_guid from vm_static where vm_name='alma8.x')); disk_id | wipe_after_delete |
4.5.3.2 propagate_errors | disk_alias | disk_description | shareable | sgio | disk_storage_type | cinder_volume_type | disk_content_type | backup | backup_mode --------------------------------------+-------------------+------------------+------------+------------------+-----------+------+-------------------+--------------------+-------------------+ --------+------------- d55e6738-67d6-441f-a38f-86fc14f248cf | f | Off | Alma_8_8.7 | 8.7 | f | | 0 | | 0 | None | (1 row) You are right, making a template from a vm doesn't effectly enable the incremental backup on the template disk, even if it is initially enabled on the vm disk. It seems to be a bug.
