主机和来宾都是CentOS 6. Guest有一个监听端口15672的pipe理面板，我无法从外部访问。
从客人， curl localhost:15672和curl vm1:15672给我的面板的预期内容。
我可以ping它
# ping vm1 PING vm1 (10.2.8.72) 56(84) bytes of data. 64 bytes from 10.2.8.72: icmp_seq=1 ttl=64 time=0.087 ms
但不能访问面板。
# curl vm1:15672 curl: (7) couldn't connect to host
我是按照本页给出的指示，当我到brctl show ，我的输出是略有不同的显示，但我不知道是否相关。
# brctl show bridge name bridge id STP enabled interfaces br0 8000.842b2b78ff80 no em1 vnet0 virbr0 8000.5254000ea9ec yes virbr0-nic

我相信你们都需要更多的信息，但是我不了解这个问题。
我错过了什么？
这个问题最终成为来宾防火墙阻止应用程序端口，而不是kvm或桥接相关
