当遇到“no suitable device found for this connection”这样的错误时,这通常指示着系统无法找到或正确识别用于建立特定连接所需的硬件设备。这个问题可能涉及多个层面,包括硬件、驱动程序、网络设置等。以下是根据您提供的提示,分点进行的详细解答: 1. 确认用户设备的硬件和驱动程序是否安装正确 硬件检查: 确保所有相...
执行命令: ifup lo 时,Centos 无法获取IP报错:No suitable device found for this connection device lo not available because device is strictly unmanaged 1. 错误现象 No suitable device found for this connection (device lo not available because device is strictly unmanaged). 执行systemctl restart network...
错误“No suitable device found for this connection”通常是由于网卡设备未被正确识别或配置文件问题导致的。解决方法包括检查网卡配置文件,确保设备名称和UUID正确,并禁用NetworkManager服务以避免冲突。 在CentOS 7中,网络配置是确保系统正常运行的关键部分,有时用户可能会遇到“No suitable device found for this connec...
但是有时候在虚拟机挂起或关机后,再次重启该虚拟机后,查看虚拟机服务器IP发现之前配置的IP地址未生效,使用ifup再次开启网卡提示: 错误:连接激活失败:No suitable device foundforthis connection (device virbr0 not available because profile is not compatible with device (mismatching interface name)). 检查发现是...
原因是Ubuntu18使用netplan来管理网络配置,后端默认使用的是network服务,通过nmcli工具管理网络时可能就会提示no suitable device found for this connection。 此时执行nmcli device 命令显示这些接口state为unmanaged未被管理的状态。即使执行过nmcli networking on,nmcli networking也显示enabled了,接口还是unmanaged状态。 在...
