安装ethtool工具

// centos
yum install ethtool

查看网卡名称

// ip 
ip addr

输出如下

[root@izbp1eknfaoihzckx0mn9tz ~]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:16:3e:17:8b:e1 brd ff:ff:ff:ff:ff:ff

       valid_lft 313521987sec preferred_lft 313521987sec
       

查看所有网卡的PCI地址

// install 
 yum install pciutils
//check
lspci | grep Eth

输出如下

[root@izbp1eknfaoihzckx0mn9tz ~]# lspci | grep Eth
00:05.0 Ethernet controller: Red Hat, Inc Virtio network device
       

##查看网卡与PCI地址对应关系：

//check
ethtool -i eth0

输出如下

[root@izbp1eknfaoihzckx0mn9tz ~]# ethtool -i eth0
driver: virtio_net
version: 1.0.0
firmware-version: 
expansion-rom-version: 
bus-info: 0000:00:05.0
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

       

网卡eth0的pci地址是

bus-info: 0000:00:05.0
