使用本命令列出网卡id

lspci -k | grep -i ethernet

root@pve:~# lspci -k | grep -i ethernet
08:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)
08:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)
0a:00.0 Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03)

然后0000:08:00.0替换成自己的

比如0000:08:00.0

cat /sys/bus/pci/devices/0000:08:00.0/sriov_totalvfs

这里8 显示这个网口能开7个VF网口

这种就是不支持

开启网卡sriov代码

cd /etc/systemd/system

新建文件 wksriov.service

enp8s0f0修改成自己对应的网卡

[Unit]
Description=Script to enable SR-IOV on boot

[Service]
Type=simple

start SR-IOV

ExecStartPre=/usr/bin/bash -c '/usr/bin/echo 7 > /sys/class/net/enp8s0f0/device/sriov_numvfs'

set VF MAC

ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set dev enp8s0f0 vf 0 mac 00:80:00:00:00:00'
ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set dev enp8s0f0 vf 1 mac 00:80:00:00:00:01'

ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set dev enp8s0f0 vf 6 mac 00:80:00:00:00:06'

set PF up

ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set enp8s0f0 up'

set VF up

ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set enp8s0f0v0 up'
ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set enp8s0f0v1 up'
ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set enp8s0f0v2 up'
ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set enp8s0f0v3 up'
ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set enp8s0f0v4 up'
ExecStartPre=/usr/bin/bash -c '/usr/bin/ip link set enp8s0f0v5 up'
ExecStart=/usr/bin/bash -c '/usr/bin/ip link set enp8s0f0v6 up'

Restart=on-failure

[Install]
WantedBy=multi-user.target

systemctl daemon-reload

systemctl enable wksriov.service

reboot

cd /home

新建文件 sr-iov-registermacaddr.sh

防止VF网络和主机网络不能互相访问

enp10s0修改成自己pve管理网口名字

11月1日更新

可以看到我这里是pve

如果你的不是pve那就把这两个pve都改成你节点的名称

CTCONFDIR=/etc/pve/nodes/pve/lxc

VMCONFDIR=/etc/pve/nodes/pve/qemu-server

就像这样

#!/usr/bin/bash
#
# vf_add_maddr.sh Version 1.1
# Script is based on kriss35
# Update by Rama: Added vmbridge macaddress itself, simplified, systemd-service(RestartOnFailure) Compatible and speeded up with a tmpfile(one readout).
# Usage: execute directly without arguments, make an systemd-service or add it to crontab to run every x Minutes.
#
CTCONFDIR=/etc/pve/nodes/pve/lxc
VMCONFDIR=/etc/pve/nodes/pve/qemu-server
IFBRIDGE=enp10s0
LBRIDGE=vmbr0
TMP_FILE=/tmp/vf_add_maddr.tmp
 
C_RED='\e[0;31m'
C_GREEN='\e[0;32m'
C_NC='\e[0m'
 
if [ ! -d $CTCONFDIR ] || [ ! -d $VMCONFDIR ]; then
        echo -e "${C_RED}ERROR: Not mounted, self restart in 5s!${C_NC}"
        exit 1
else
        MAC_LIST_VMS=" $(cat ${VMCONFDIR}/*.conf | grep bridge | grep -Eo '([[:xdigit:]]{1,2}[:-]){5}[[:xdigit:]]{1,2}' | tr '[:upper:]' '[:lower:]') $(cat ${CTCONFDIR}/*.conf | grep hwaddr | grep -Eo '([[:xdigit:]]{1,2}[:-]){5}[[:xdigit:]]{1,2}' | tr '[:upper:]' '[:lower:]')"
        MAC_ADD2LIST="$(cat /sys/class/net/$LBRIDGE/address)"
        MAC_LIST="$MAC_LIST_VMS $MAC_ADD2LIST"
        /usr/sbin/bridge fdb show | grep "${IFBRIDGE} self permanent" > $TMP_FILE
 
        for mactoregister in ${MAC_LIST}; do
                if ( grep -Fq $mactoregister $TMP_FILE ); then
                        echo -e "${C_GREEN}$mactoregister${C_NC} - Exists!"
                else
                        /usr/sbin/bridge fdb add $mactoregister dev ${IFBRIDGE}
                        echo -e "${C_RED}$mactoregister${C_NC} - Added!"
                fi
        done
        exit 0
fi

chmod +x sr-iov-registermacaddr.sh

./sr-iov-registermacaddr.sh

如果你VF网卡有直通给Ubuntu 那记得在控制台修改网卡名字

sudo -i

nano /etc/netplan/00-installer-config.yaml

群晖docker安装iperf 服务端命令 一次性

docker run -it –rm –name=iperf-srv –network=host clearlinux/iperf -s

apt-get install iperf3

iperf3 -c 192.168.3.191 -i1 -t60 -P8
