早上好，超级用户，我陷入了困境。
我有两台服务器，os-net和vmhost3，通过交叉电缆在各自的 10Gbps 接口上连接在一起。两台服务器都运行 Ubuntu 14.04 LTS，唯一的区别是它os-net在 ESXi 上虚拟化。虚拟机有自己的 VMKernel 端口，将其连接到 ESXi 服务器上的 10Gbps 接口。
我遇到的问题是尝试让两个服务器相互通信，如果我os-net通过vmhost3（ping -c 4 10.0.0.2）执行 ping 操作，它会发送 ARP 请求并得到响应，但是当它发送 ICMP 回显请求时，它不会收到任何回复。
以下是来自 wire shark 的捕获os-net（tshark -i eth0）

如果我尝试反向操作并尝试 pingvmhost3我os-net会得到这个捕获 (tshark -i em2)
