Reason for failure (if possible)

The BMH cannot be provisioned because the "image is not valid for use".

From Ironic logs:

Anything else we need to know?

We thought first that the issue was that we did not specify the image hash, but this has been ruled out in #2103.

IIRC @Rozzii said this coincides with new ironic build on the same date.

[lentzi90]

I wonder if it could be related to this: https://bugs.launchpad.net/nova/+bug/2091114
We did a temporary workaround for it in CAPO.

[Rozzii]

I was expecting this originally: https://opendev.org/openstack/ironic/commit/669304bc0c6b2762c872b71297480c4b4ffdb554

[Rozzii]

Based on the quay artifacts, I would expect the root cause landed in ironic between Nov 6 and Dec 3.

[lentzi90]

I think you are correct that this came with oslo.utils.
The specific commit that introduced it in oslo.utils is here: openstack/oslo.utils@91af49b
Then there was some related changes that looks like they would be relevant to the live-iso use-case: openstack/oslo.utils@3d4ae16
I haven't figured out yet how we are supposed to "allow" multiple formats.

[Rozzii]

I think in the test system we supposed to have the safety check diasbled as we don't really care, but I have thought that enabling all the formats is the default.

BMO 0.8 virtualmedia works, where ironic is pinned to 26.0: #2111

[Rozzii]

I have created a bug report on Ironic side and continued working on this: https://bugs.launchpad.net/ironic/+bug/2091611

We could discuss reverting the pinning #2112 as there is a possibility to turn off the feature that initiates the problematic image format inspection, so that we could continue the testing of other Ironic features.
