Question

我需要您的帮助来解决一些奇怪的问题我们正在尝试在centos 7服务器上创建ifcfg-eth1网络设备。

我们在ifcfg-eth1文件中使用以下信息；

TYPE=Ethernet
BOOTPROTO=static
DEVICE=eth1
ONBOOT=yes
IPADDR=192.168.101.61
NETMASK=255.255.255.0
GATEWAY=192.168.100.1
DNS1=8.8.8.8
DNS2=8.8.4.4

ifcfg-eth0可以正常工作，但是当我们创建ifcfg-eth1时，会出现以下错误；

No suitable device found for this connection.

这可能是什么问题？可能与我们的网卡有关吗？还是问题可能出在其他地方？

我们对ifcfg-eth0的设置是;

TYPE=Ethernet
PROXY_METHOD=static
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=eth0
UUID=f3d98d60-6062-4b70-a14c-7ac4040bd403
DEVICE=eth0
ONBOOT=yes
IPADDR=192.168.100.60
PREFIX=24
GATEWAY=192.168.100.1
DNS1=8.8.8.8

谢谢您的建议。非常感谢您的帮助。

过去三天，我们已经在同一个问题上苦苦挣扎。
