在2台虚拟机和1台主机中，一次只能从局域网访问2台虚拟机

我有一个configuration了两个虚拟机的VMware vSphere虚拟机pipe理程序。 我需要能够到达主机（用于configuration等）以及来自我的客户端（也在同一子网中）的两个虚拟机。 我想build立一个PoC Hadoop集群，客户端需要连接到所有的虚拟机。

昨天，我可以ping主机和虚拟机的一个，但不是另一个。 从无法访问的虚拟机上ping可达的虚拟机，以及ping主机（如果我没有记错的话）。

今天，我能够ping两个虚拟机，但不是主机，我没有改变任何东西。

所有三个都configuration了静态IP，但无法访问的似乎不是networking的一部分（也许ARP请求不能达到它或某事）。 检查我的客户端上的ARP表只是确认无法访问的主机的IP有无效的条目。 我试图删除无效的条目，甚至完全刷新caching，但无济于事。

• 性能影响使用完整的一个子网
• 在使用外部网关的debian上访问Internet
• Avaya 4850 GTS＆VSP 7000 – build立光纤中继线，无MLT
• 将两个子网与相同的默认网关组合在一起
• 将build立一个VPN防止他人看到什么是在networking上？

我检查了没有MAC地址冲突，发现虚拟机和主机都有不同的MAC地址。 主机名也是不同的。 而且分配的IP很明显。

我想到了路由器的端口保护，但似乎没有道理，因为同一端口上至less有两个IP。 此外，我不能轻易检查是否激活，因为我没有访问路由器。

基本的networkingconfiguration是：

VM Host: 172.16.40.11 ------ Gateway: 172.16.40.1 ----- Client: 172.16.40.22 VM 1: 172.16.40.191 -| VM 2: 172.16.40.193 -| 

在客户端上显示主机不可用的简短命令行会话：

我重新启动主机并重新启动虚拟机，我回到了昨天的情况：

同时在VM1上，我可以连接到主机和VM2，以及网关：

 [hadoop@hadoop1 ~]$ ping 172.16.40.1 PING 172.16.40.1 (172.16.40.1) 56(84) bytes of data. 64 bytes from 172.16.40.1: icmp_seq=1 ttl=255 time=0.593 ms 64 bytes from 172.16.40.1: icmp_seq=2 ttl=255 time=0.591 ms ^C --- 172.16.40.1 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1307ms rtt min/avg/max/mdev = 0.591/0.592/0.593/0.001 ms [hadoop@hadoop1 ~]$ ping 172.16.40.11 PING 172.16.40.11 (172.16.40.11) 56(84) bytes of data. 64 bytes from 172.16.40.11: icmp_seq=1 ttl=64 time=1.02 ms 64 bytes from 172.16.40.11: icmp_seq=2 ttl=64 time=0.109 ms ^C --- 172.16.40.11 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1103ms rtt min/avg/max/mdev = 0.109/0.567/1.025/0.458 ms [hadoop@hadoop1 ~]$ ping 172.16.40.191 PING 172.16.40.191 (172.16.40.191) 56(84) bytes of data. 64 bytes from 172.16.40.191: icmp_seq=1 ttl=64 time=0.033 ms 64 bytes from 172.16.40.191: icmp_seq=2 ttl=64 time=0.018 ms ^C --- 172.16.40.191 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1194ms rtt min/avg/max/mdev = 0.018/0.025/0.033/0.009 ms [hadoop@hadoop1 ~]$ ping 172.16.40.193 PING 172.16.40.193 (172.16.40.193) 56(84) bytes of data. 64 bytes from 172.16.40.193: icmp_seq=1 ttl=64 time=1.98 ms 64 bytes from 172.16.40.193: icmp_seq=2 ttl=64 time=0.134 ms ^C --- 172.16.40.193 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1587ms rtt min/avg/max/mdev = 0.134/1.058/1.982/0.924 ms 

但在VM2上，我只能ping通主机和VM1，而不是网关：

最后但并非最不重要的是，主机也可以ping通虚拟机和网关：

 ~ # ping 172.16.40.1 PING 172.16.40.1 (172.16.40.1): 56 data bytes 64 bytes from 172.16.40.1: icmp_seq=0 ttl=255 time=0.545 ms 64 bytes from 172.16.40.1: icmp_seq=1 ttl=255 time=3.338 ms --- 172.16.40.1 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 0.545/1.942/3.338 ms ~ # ping 172.16.40.11 PING 172.16.40.11 (172.16.40.11): 56 data bytes 64 bytes from 172.16.40.11: icmp_seq=0 ttl=64 time=0.055 ms --- 172.16.40.11 ping statistics --- 1 packets transmitted, 1 packets received, 0% packet loss round-trip min/avg/max = 0.055/0.055/0.055 ms ~ # ping 172.16.40.191 PING 172.16.40.191 (172.16.40.191): 56 data bytes 64 bytes from 172.16.40.191: icmp_seq=0 ttl=64 time=0.131 ms 64 bytes from 172.16.40.191: icmp_seq=1 ttl=64 time=0.124 ms --- 172.16.40.191 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 0.124/0.128/0.131 ms ~ # ping 172.16.40.193 PING 172.16.40.193 (172.16.40.193): 56 data bytes 64 bytes from 172.16.40.193: icmp_seq=0 ttl=64 time=0.205 ms 64 bytes from 172.16.40.193: icmp_seq=1 ttl=64 time=0.128 ms --- 172.16.40.193 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 0.128/0.166/0.205 ms 

vSphere中networkingconfiguration的屏幕截图（hadoop1和hadoop3是两个虚拟机）：

这里发生了什么？ 我怎样才能进一步诊断发生了什么？

我怀疑由于某种原因，只有两个IP被允许来自networking接口，但是什么可能导致这个问题，我该如何解决？
