CentOS 7이 네트워크 인터페이스 컨트롤러를 감지하지 못합니다

CentOS 7은 원격 서버에 최소한으로 설치됩니다. 두 개의 NIC가 있습니다. 내가 작업한 다른 서버와 동일한 설정입니다. 그러나 그 중 하나가 작동하지 않는 것 같습니다.

[root@home network-scripts]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether d0:50:99:d3:10:2c brd ff:ff:ff:ff:ff:ff

[root@home network-scripts]# nmcli d
DEVICE  TYPE      STATE      CONNECTION
enp4s0  ethernet  connected  enp4s0
lo      loopback  unmanaged  --

ifcfg-enp4s0그러나 및 에 대한 ifcfg-eno1문서 가 있습니다 /etc/sysconfig/network-scripts/.

이것은 ifcfg-eno1:

내가 실행할 때 :

[root@home network-scripts]# ifup eno1
Error: Connection activation failed: No suitable device found for this connection.

산출

[root@home network-scripts]# lshw -class network

위의 내용이 무엇을 의미하는지 잘 모르겠습니다 UNCLAIMED.

또한 커널 출력을 확인해 보았습니다.

[root@home network-scripts]# dmesg | grep -i "Network Connection"
[    2.488019] igb 0000:04:00.0: Intel(R) Gigabit Ethernet Network Connection

그리고 일부 lspci출력:

[root@home net]# lspci | grep Connection

이것이 드라이버 문제인지는 확실하지 않습니다(다음은자주하는 질문, 그러나 아래 출력에 따르면 두 장치 모두 적절한 드라이버가 설치되어 있습니다.

운영 체제에 소프트웨어 문제가 있는지 또는 물리적 포트/마더보드에 하드웨어 문제가 있는지 어떻게 알 수 있습니까?

완전히 분명한 것을 놓치고 있습니까?

편집: 관련 드라이버 출력은 다음과 같습니다 lspci -k.
