KVM端口绑定

KVM端口绑定

我跟着在我的 ubuntu 服务器上安装 KVM 虚拟机的教程。现在我需要将一个端口从客户机绑定到主机。我尝试了几个教程来绑定端口,但都没有用。

我的设置是:


主机:Ubuntu 14.04,IP:192.168.122.1(KVM IP),我可以访问主机的 IP:10.211.55.4

eth1      Link encap:Ethernet  HWaddr 00:1c:42:d0:7a:75  
      inet addr:10.211.55.4  Bcast:10.211.55.255  Mask:255.255.255.0

访客:Ubuntu 14.04,IP:192.168.122.141

eth0      Link encap:Ethernet  HWaddr 52:54:00:9e:7b:58

      UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

      RX bytes:33867 (33.8 KB)  TX bytes:24842 (24.8 KB)

有人能帮我把客户机上的 80 端口绑定到主机吗,这样我就可以从客户机上获取 web 服务器了http://10.211.55.4

提前致谢!

您可以将 VM iface 桥接到“外部”网络,或者设置 iptables 并为所需的端口创建 DNAt 条目。
