    • A.[Natalie] We support it but it’s not formally released yet. Will be formally delivered in 18.09.
    • BB - Kernel bypass uses UIO possible to do. [natalie] check support for VF for onboard NICs
    • Q. If Yes, is it a hardware level support or supported in musdk also ?
    • A.[Natalie] MUSDK is not relevant here. Intel NICs are using DPDK and ARM infrastructure directly. We support PCIE SR-IOV with both v4.4 and v4.14 kernels
    • Q. Has anybody tested containers (docker) and any container orchestration system on mcbin (e.g Docker Swarm or Kubernetes) ?
    • A.[Natalie] Yes.
    • Q. K8s or Docker Swarn ?
    • A. [Bin Arm Internal] K8s is good choice version(1.9.4). Use kubeadm to install k8s cluster.
    • Q. VM inside a container works on ARM ?
    • A. [Bin ARM Internal] Use Kata and Runv. Kata/Runv is the solution of hardware-virtualized containers.
    • Q. Container within a Container(nested) works on ARM ?
    • A.[Bin ARM Internal] ‘Docker in docker’ or ‘Docker of Docker’ can works well on Arm platform.
