ci: Pin older OVN-Kubernetes branches to version-matched CNV nightly#78122
Conversation
Set CNV_PRERELEASE_LATEST_CHANNEL to false for release-4.17 through release-4.22 branches. This causes the kubevirt-install step to use version-matched CNV nightly (e.g. nightly-4.22 for OCP 4.22) instead of the bleeding-edge nightly-4.99. CNV nightly-4.99 recently picked up QEMU from RHEL 9.8 which introduces the pc-q35-rhel9.8.0 machine type as the default. This machine type is not available on older OCP release nodes, causing virt-launcher pods to fail scheduling with: 0/6 nodes are available: 6 node(s) didn't match Pod's node affinity/selector The mismatch occurs because the CNV CSV sets the default machine type to pc-q35-rhel9.8.0, but the node's QEMU only supports up to pc-q35-rhel9.6.0, so the required node label machine-type.node.kubevirt.io/pc-q35-rhel9.8.0 is never created. Branches main, release-4.23, release-5.0, and release-5.1 continue to use nightly-4.99 as they track OCP versions compatible with the latest CNV builds.

affinity/selector
The mismatch occurs because the CNV CSV sets the default machine type to pc-q35-rhel9.8.0, but the node's QEMU only supports up to pc-q35-rhel9.6.0, so the required node label
machine-type.node.kubevirt.io/pc-q35-rhel9.8.0 is never created.
Branches main, release-4.23, release-5.0, and release-5.1 continue to use nightly-4.99 as they track OCP versions compatible with the latest CNV builds.
