Hi, I am so frustrated on setting up the tunnel between the open vswitch on xenservers. I have two xenserver. I use one NIC as the interface to talk to another remote xenserver host. I add a port name gre1 on the xenbr1 for both two servers.
I run, *ovs-vsctl add-port xenbr1 gre1 -- set interface gre1 type=gre options:remote_ip=129.X.X.X (public ip address on xenbr1 of xenserver host 1 )* *ovs-vsctl add-port xenbr1 gre1 -- set interface gre1 type=gre options:remote_ip=198.X.X.X (public ip address on xenbr1 of xenserver host 2 )* I run this command on both xenserver host. They are success to be run. I check the *ovs-vsctl list-ports xenbr1* on both xenserver host. Both of two server shows : eth1 (physical NIC attached to xenbr1) gre1 (The one I created above) Sometimes, It has another port shown which is vif4.1 (is that the VIF of one VM with VLAN ID ? because I attach one virtual interface for each VM, that interface has vlan id say 100 on it.) Within each xenserver, I created each VM (two VM has private ip address but in the same subnet. say 172.16) on each site, But they still can not talk to each other. Is that all command I should type in ? Any idea ? Thanks very much, -- Best regards, Terry Xing.
