Hi,
I think, this is definitely a bug.
In engine.log, I see some of those entries:
2018-11-15 09:11:02,668Z INFO
[org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default

VM_SLA_POLICY_STORAGE(10,551), VM qwe SLA Policy was set. Storage policy
changed for disks: [tmp, log, root, qwe_var]
I see these entries for some of the VMs for some of their disks, but this
policy is set for about 80 VMs and all of their disks.
In the logs, I see only few of them and there is no error about not being able
to set the SLA.
Can please someone give me hint on how to force updating the QoS SLA for all
affected VMs. An API call would also help.
Maybe also someone else can confirm that this is a bug, because I would create
a bug report.

Betreff: [ovirt-users] How to force a QoS IO limit update to all disks
Hi,
oVirt version: 4.2.5.1
I have a strange problem with IO limiting.
I have a storage domain for our dev environment and I have set the default Disk
Profile to a QoS rule with IO limit enabled.
This rule is working so far, but when I change the QoS rule of this default
Disk Profile to a different IO limit, all the disks have still the old limit
active.
Only when I edit the disk and click OK without changing anything, I see also in
Events, that the new IO limit is set.
This behavior would cause me a lot of work, because we have several 100s of
disks and I can't edit all, only to have new QoS active.
Is there another way to do this bulk change of disk IO limit?
What data do you need to have a look on?
EDIT:
I saw now, that the QoS policy is automated updated on some VMs and there only
on some disks, but not on all. Is there a rate limit active or so?
