Description of problem:
When installing the SR-IOV operator in an OKD cluster, the entrypoint.sh script in the following components (i.e., sriov-cni, ib-sriov-cni, and rdma-cni) fails to start.
The reason for the failure is that these scripts depend on the info in the os-release file, which changes in RHEL10 for OKD deployments (see sample below).
# /etc/os-release NAME="CentOS Stream CoreOS" VERSION="10.0.20251023-0 (Coughlan)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="10" PLATFORM_ID="platform:el10" PRETTY_NAME="CentOS Stream CoreOS 10.0.20251023-0 (Coughlan)" ANSI_COLOR="0;31" LOGO="fedora-logo-icon" CPE_NAME="cpe:/o:centos:centos:10" HOME_URL="https://centos.org/" VENDOR_NAME="CentOS" VENDOR_URL="https://centos.org/" BUG_REPORT_URL="https://issues.redhat.com/" REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux 10" REDHAT_SUPPORT_PRODUCT_VERSION="CentOS Stream" OSTREE_VERSION='10.0.20251023-0' VARIANT=CoreOS VARIANT_ID=coreos OPENSHIFT_VERSION="4.20"
Version-Release number of selected component (if applicable):
4.21 and any OKD release that use RHEL10.
How reproducible:
Always
Steps to Reproduce:
- Deploy an OKD cluster booting from a RHEL10 ISO (e.g., 4.20.0-0.okd-scos-2025-11-16-192318).
- Install the SR-IOV operator from RH catalogs.
- Watch the initContainers of the sriov-network-config-daemon-xxx pod at the openshift-sriov-network-operator namespace.
Actual results:
-> oc get pod NAME READY STATUS RESTARTS AGE sriov-device-plugin-jj4d2 1/1 Running 4 20h sriov-network-config-daemon-fzjwr 0/1 Init:CrashLoopBackOff 261 (2m55s ago) 20h sriov-network-operator-cc5899d4b-klxcx 1/1 Running 4 20h
