CentOS 7 组队桥接网络仅适用于单个 NIC

几天来我一直在尝试将我的服务器网卡组合起来，然后桥接以在虚拟化盒（KVM）上使用。我已经设法将其连接到网络上，并且至少可以 ping google，但是，它仅在我插入第二个网卡（eno2）时才有效。如果我仅在第一个 NIC (eno1) 中使用电缆，则本地网络上的路由器看不到服务器。

我查看了文档和无数的论坛。我发现让我“最接近”的最佳资源是这个网站：https://myredhatcertification.com/2015/04/09/software-bridge-on-top-of-the-teaming-device/。不确定我做错了什么。顺便说一句，我的 KVM 虚拟机没有使用任何一个 NIC 的网络。但是，当我在主机上建立网络并可靠后，可以查看这一点。

我已停止并禁用 NetworkManager（但仍已安装）。

以下是相关输出和文件（如果您想查看更多，请询问）

ip as 这是网线插入eno2时的情况
