Bringing up interface eth0: Error: No suitable device found: no device found for connection ‘System eth0’. [FAILED]

1. Description: virtual machine configuration IP restart network card: service network restart error message:

The error information is as follows:

[root@localhost network-scripts]# vim ifcfg-eth0
[root@localhost network-scripts]# 
[root@localhost network-scripts]# service network restart
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:  Error: No suitable device found: no device found for connection 'System eth0'.
                                                           [FAILED]

2. This problem occurs because the network card actually assigned to the virtual machine does not match the network card information in the configuration file

1. The actual network card information allocated to the virtual machine is: [hwaddr 00:0c: 29:7f: B6: FF]

root@localhost /]# ifconfig
eth1      Link encap:Ethernet  HWaddr 00:0C:29:7F:B6:FF  
          inet6 addr: fe80::20c:29ff:fe7f:b6ff/64 Scope:Link

          RX bytes:3760 (3.6 KiB)  TX bytes:3760 (3.6 KiB)

2. The network card information in the configuration file is:

vim /etc/sysconfig/network-script/ifcfg-eth0

DEVICE="eth0"
BOOTPROTO="static"
IPV4_FAILURE_FATAL="yes"
BOOTPROTO="dhcp"
HWADDR="00:0C:29:7F:B6:8A"
IPV6INIT="yes"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="5c4e89fb-eced-4d66-962a-e5f6e565ec26"
IPADDR="192.168.25.135"
NETMASK="255.255.255.0"
GATEWAY="192.168.25.1"
DNS1="192.168.25.1"

3. Modification method: the above configuration files are configured according to the network card actually allocated to the virtual machine, that is:

HWADDR="00:0C:29:7F:B6:8A" Modify to HWADDR="00:0C:29:7F:B6:FF"
Save the pair to exit: restart the NIC: service network restart Correct
