Hi developer, i got a problem and need your help!(my english not very good) My KVM host in IDC, and there are some restrict in there lead to me connect to KVM host by port 22 or 16509 impossible. In generally If i want login my KVM host i must login in to a "stepping stones" first, then login to that KVM host.( Now assume that the KVM host ip is 1.1.1.1 and the "stepping stones" ip is 2.2.2.2). So i use the "portforwarding" (i used the manner of "qemu+tcp" to connect KVM host, the default port is 16509), I visit the port 16509 in "stepping stones" machine 1.1.1.1 and then 1.1.1.1 port forwarding to 2.2.2.2:16509. And then my virt-manager connect KVM host successful！ But my trouble is comming too. I can't use virt-manager to control my guest by graphic. I "portforwarding" the port 5911(i had already defined my guest vnc port), but is unuseful. I used command "netstat -antl" in KVM host found that : tcp 0 0 127.0.0.1:5911 0.0.0.0:* LISTEN tcp 0 0 1.1.1.1:16509 2.2.2.2:63325 ESTABLISHED tcp 0 0 0.0.0.0:16509 0.0.0.0:* LISTEN As you see, 5911 listen into localhost(127.0.0.1), but 16509 listen into the 1.1.1.1 and 0.0.0.0. So I think if 5911 listen 0.0.0.0 or 1.1.1.1 everything is ok. Here is my virt-manager.log: [Thu, 28 Mar 2013 00:57:16 virt-manager 3242] DEBUG (engine:471) window counter incremented to 2 [Thu, 28 Mar 2013 00:57:16 virt-manager 3242] DEBUG (console:1078) Starting connect process for proto=vnc trans=tcp connhost=2.2.2.2 connuser=root connport=None gaddr=127.0.0.1 gport=5911 gsocket=None [Thu, 28 Mar 2013 00:57:16 virt-manager 3242] DEBUG (console:374) VNC connecting to 2.2.2.2:5911 [Thu, 28 Mar 2013 00:57:18 virt-manager 3242] DEBUG (console:961) Viewer disconnected How can i use virt-manager to control my guest by graphic? thank you very much!!!
