Hello Devs, I hope this email finds you well. I am reaching out to seek assistance regarding an issue I am facing in DPDK within my Kubernetes cluster.
I have deployed a Kubernetes cluster v1.26.0, and I am currently running network testing through DPPD-PRoX (commit/02425932<https://github.com/opnfv/samplevnf/commit/02425932>) using DPDK (v22.11.0). I have deployed 3 pairs of PODs (3 server pods and 3 client pods) on a single K8 node. The server generates and sends traffic to the receiver pod. During the automated testing, I encounter an error: "Error in rte_eal_init()." This error occurs randomly, and I am unable to determine the root cause. However, this issue does not occur when I use a single pair of PODs (1 server pod and 1 client pod). The traffic is sent and received through the sriov NICs. PFB the software catalogue I am using: DPPD-PRoX: commit/02425932<https://github.com/opnfv/samplevnf/commit/02425932> DPDK version: v22.11.0 DPDK driver: vfio-pci SRIOV VF driver: iavf POD OS: Ubuntu 20.04 POD Kernel: 4.18.0-372.9.1.el8.x86_64 Kubernetes: v1.26.0 Error logs: EAL: Detected CPU lcores: 104 EAL: Detected NUMA nodes: 2 EAL: Detected shared linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'VA' EAL: VFIO support initialized EAL: Cannot allocate memzone list EAL: FATAL: Cannot init memzone EAL: Cannot init memzone Supports Intel RDT Monitoring capability RDT-A.
