Timer test - 2. Device Interrupt Test - 3. Packet forwarding (DPDK OVS) - 4. Packet Forwarding (SR-IOV) - 5. Bare-metal Packet Forwarding - -Dependencies ------------- - -1. OPNFV Project: “Characterize vSwitch Performance for Telco NFV Use Cases” - (VSPERF) for performance evaluation of ivshmem vs. vhost-user. -2. OPNFV Project: “Pharos” for Test Bed Infrastructure, and possibly - “Yardstick” for infrastructure verification. -3. There are currently no similar projects underway in OPNFV or in an upstream - project -4. The relevant upstream project to be influenced here is QEMU/KVM and - libvirt. -5. In terms of HW dependencies, the aim is to use standard IA Server hardware - for this project, as provided by OPNFV Pharos. - - -Reference ---------- - -https://wiki.opnfv.org/display/kvm/ -- cgit 1.2.3-korg
