252. vhost-user/virtio-pmd pvp bonding test plan¶
252.1. Description¶
The Link Bonding functions make it possible to dynamically create and manage link bonding devices from within testpmd interactive prompt, below are the introduction of seven bonding modes： - Mode = 0 (balance-rr) Round-robin policy: (default). - Mode = 1 (active-backup) Active-backup policy: Only one NIC slave in the bond is active. - Mode = 2 (balance-xor) XOR policy: Transmit network packets based on the default transmit policy. - Mode = 3 (broadcast) Broadcast policy: Transmit network packets on all slave network interfaces. - Mode = 4 (802.3ad) IEEE 802.3ad Dynamic link aggregation. - Mode = 5 (balance-tlb) Adaptive transmit load balancing. - Mode = 6 (balance-alb) Adaptive load balancing.
252.2. Test case 1: vhost-user/virtio-pmd pvp bonding test with mode 0¶
Flow: TG–> NIC –> Vhost –> Virtio3 –> Virtio4 –> Vhost–> NIC–> TG
Bind one port to vfio-pci,launch vhost by below command:
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-6 -n 4 --file-prefix=vhost --vdev 'net_vhost,iface=vhost-net,client=1,queues=1' --vdev 'net_vhost1,iface=vhost-net1,client=1,queues=1' --vdev 'net_vhost2,iface=vhost-net2,client=1,queues=1' --vdev 'net_vhost3,iface=vhost-net3,client=1,queues=1' -- -i --port-topology=chained --nb-cores=4 --txd=1024 --rxd=1024 testpmd>set fwd mac testpmd>start
Bootup one vm with four virtio-net devices:
qemu-system-x86_64 -name vm0 -enable-kvm -chardev socket,path=/tmp/vm0_qga0.sock,server,nowait,id=vm0_qga0 \ -device virtio-serial -device virtserialport,chardev=vm0_qga0,name=org.qemu.guest_agent.0 \ -daemonize -monitor unix:/tmp/vm0_monitor.sock,server,nowait \ -net nic,macaddr=00:00:00:c7:56:64,addr=1f \ -net user,hostfwd=tcp:127.0.0.1:6008-:22 \ -chardev socket,id=char0,path=./vhost-net,server \ -netdev type=vhost-user,id=netdev0,chardev=char0,vhostforce \ -device virtio-net-pci,netdev=netdev0,mac=52:54:00:00:00:01 \ -chardev socket,id=char1,path=./vhost-net1,server \ -netdev type=vhost-user,id=netdev1,chardev=char1,vhostforce \ -device virtio-net-pci,netdev=netdev1,mac=52:54:00:00:00:02 \ -chardev socket,id=char2,path=./vhost-net2,server \ -netdev type=vhost-user,id=netdev2,chardev=char2,vhostforce \ -device virtio-net-pci,netdev=netdev2,mac=52:54:00:00:00:03 \ -chardev socket,id=char3,path=./vhost-net3,server \ -netdev type=vhost-user,id=netdev3,chardev=char3,vhostforce \ -device virtio-net-pci,netdev=netdev3,mac=52:54:00:00:00:04 \ -cpu host -smp 8 -m 4096 \ -object memory-backend-file,id=mem,size=4096M,mem-path=/mnt/huge,share=on \ -numa node,memdev=mem -mem-prealloc -drive file=/home/osimg/ubuntu16.img -vnc :10
On vm, bind four virtio-net devices to vfio-pci:
./usertools/dpdk-devbind.py -b vfio-pci xx:xx.x xx:xx.x xx:xx.x xx:xx.x
Launch testpmd in VM:
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 0-5 -n 4 -- -i --port-topology=chained --nb-cores=5
Create one bonded device in mode 0 on socket 0:
testpmd>create bonded device 0 0 # create bonded device (mode) (socket) created new bonded device on (port 4) # in this case, already has port 0,1,2,3 for vdev, so the bonded device port is 4
Add three vdev (port 0,1,2) to link bonding device (port 4) and configure forwarding on port 3 and port 4:
testpmd>add bonding slave 0 4 # add bonding slave (slave id) (port id) testpmd>add bonding slave 1 4 testpmd>add bonding slave 2 4 testpmd>port start 4 testpmd>show bonding config 4 testpmd>set portlist 3,4 testpmd>set fwd mac testpmd>start
Send packets to nic port by packet generator.
Check port stats at VM side, there are throughput between port 3 and port 4:
testpmd>show port stats all
252.3. Test case 2: vhost-user/virtio-pmd pvp bonding test with different mode from 1 to 6¶
Bind one port to vfio-pci,launch vhost by below command:
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-6 -n 4 --file-prefix=vhost --vdev 'net_vhost,iface=vhost-net,client=1,queues=1' --vdev 'net_vhost1,iface=vhost-net1,client=1,queues=1' --vdev 'net_vhost2,iface=vhost-net2,client=1,queues=1' --vdev 'net_vhost3,iface=vhost-net3,client=1,queues=1' -- -i --port-topology=chained --nb-cores=4 --txd=1024 --rxd=1024 testpmd>set fwd mac testpmd>start

Launch testpmd in VM:
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 0-5 -n 4 -- -i --port-topology=chained --nb-cores=5
Create bonding device with mode 1 to mode 6:
testpmd> create bonded device (mode) 0
Add three vdev (port 0,1,2) to link bonding device (port 4) and configure forwarding on port 3 and port 4:
testpmd>add bonding slave 0 4 # add bonding slave (slave id) (port id) testpmd>add bonding slave 1 4 testpmd>add bonding slave 2 4 testpmd>port start 4 testpmd>show bonding config 4 testpmd>set portlist 3,4 testpmd>set fwd mac testpmd>start
