At minimum, describe the HostedCluster lookup, hosted-cluster client creation, NodePool creation, and Deployment creation failures, and add diagnostic messages to each control-plane status assertion. Keep the existing resource cleanup and explicit wait timeouts. Full details: Topology-Aware Scheduling CompatibilityExplanation PASS — The PR adds an AWS e2e cluster variant and a test.

This currently isn't running in v2-aws, from what I can tell. How will it be enabled later?

What the... you're right, the upgrade test was skipped (but the other ones ran) 🤦♂️
Need to figure out why

Looks like the AWS job in prow needs updated to set the necessary env vars for upgrade testing, we'll need it for this and for the upcoming non-karpenter AWS upgrade jobs. I'll get the change merged and then we can re-run and should see it reflected in this PR
There was a problem hiding this comment.
Actually this turned out to be a v2-ism I missed. Needed to translate env vars to the expected key for upgrade image. It won't be needed after #9420 but for now it should start working, let's see....

Now we're getting an upgrade failure, so that's progress.
I got a success locally so I'll need to dig in and see what's going on here, could be flaky

I guess I'm a little confused. Would that PR allow the initial (before upgrade) version of the HCP (only for karpenter upgrade test HC, not for karpenter test HC or for rest of v2 suites HC) to be set to the n-1 release image?
There was a problem hiding this comment.
In the test cluster specs the upgrade cluster is set to the N-1 image initially and then the test upgrades it... the way this is handled in the presubmits is extremely non-obvious. Everything resolves ultimately to the OCP_IMAGE_N1 env var. Pasting from my offline analysis:
====
For the presubmits, here's how the N-1 is passed to the guest creation........
This hypershift-resolve-nodepool-releases pre step runs to resolve node pool releases:
which calls this script:
https://github.com/openshift/release/blob/main/ci-operator/step-registry/hypershift/resolve-nodepool-releases/hypershift-resolve-nodepool-releases-commands.sh
which writes this file:
echo "export OCP_IMAGE_N${n}=\"${resolved}\"" >> "${OUTPUT_FILE}"
which the create-guests script sources:
https://github.com/openshift/release/blob/main/ci-operator/step-registry/hypershift/azure/create-selfmanaged-guests/hypershift-azure-create-selfmanaged-guests-commands.sh
if [[ -f "${SHARED_DIR}/nodepool_release_images" ]]; then
source "${SHARED_DIR}/nodepool_release_images"
fi
===
For periodics, it works through dependencies:
- as: e2e-v2-azure-self-managed
cron: 30 1,7,13,19 * * *
steps:
cluster_profile: hypershift-azure
dependencies:
OCP_IMAGE_N1: release:n1minor
env:
ENABLE_HYPERSHIFT_CERT_ROTATION_SCALE: "true"
HYPERSHIFT_AZURE_LOCATION: centralus
workflow: hypershift-azure-e2e-v2-self-managed
The AWS job configs were missing all of that and so the OCP_IMAGE_N1 is getting defaulted to the same as latest. With the new PR it should get set to N-1 for each branch

Gotcha, thanks for stepping through all that. Makes sense to me now.

…4608) The e2e-v2-aws presubmit for HyperShift release-5.0 lacked the NODEPOOL_N1_VERSION env var, causing the v2 Karpenter upgrade variant (introduced by openshift/hypershift#9397) to receive OCP_IMAGE_N1 identical to RELEASE_IMAGE_LATEST. With identical images the upgrade is a no-op and NodeClaim drift never triggers, hanging the test. Set NODEPOOL_N1_VERSION to "4.22" (N-1 for 5.0) in both public and private configs, matching the pattern already present on main. Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
