有一种情况:有 2 台虚拟计算机(定义为 A 和 B),每台运行 Ubuntu 16.04。对它们进行网络配置:
Adapter1 : Host-only with Promiscuous Allow All
Adapter2: Nat Network with Promiscuous Allow VM's
两台电脑的mac地址不同
PC A :
仅主机适配器与 mac(080027B2EBC7)
NAT 网络适配器与 mac(0800273F605C)
PC B:
host onlt 适配器 with mac( 0800272DC6FF
)
Nat 网络适配器 with mac( 080027B8CEC1
)
计算机 A:通过终端发送 ping 命令:
ping google.com
当计算机 A 正在 ping 计算机 B 上打开的 wireshark 时。
我在 PC B 的 Wireshark 上看不到我从 PC A 发送的 icmp 数据包。
两台 PC 的 ifconfig:

也许我对虚拟机网络的想法有错误的理解。
