Hi, Alex,
I tried your suggestion, it seems that the problem is still there
In host 1: I have the tunnel ready
zhunan@zhunan-PowerEdge-R210-II:~$ sudo ovs-vsctl show
[sudo] password for zhunan:
01db97ba-8174-40f6-9648-f8f14a317e2b
Bridge "br0"
Port "tunnel_to_host1"
Interface "tunnel_to_host1"
type: gre
options: {remote_ip="192.168.2.2"}
Port "br0"
Interface "br0"
type: internal
and the routing table looks like
zhunan@zhunan-PowerEdge-R210-II:~$ route

192.168.2.0 * 255.255.255.0 U 1 0 0 eth1
where 192.168.55.1 is the gateway to access internet
the devices are :

In host2:
I also build the tunnel:
cpslab@cpslab-cluster-2:~$ sudo ovs-vsctl show
[sudo] password for cpslab:

192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
where eth0 is connected with eth1 in host1
the devices are:

I think everything should be ready:
but when I'm in the VM running on host1, it still fails to ping 192.168.2.2~~
zhunan@vm0:~$ ping 192.168.2.1
PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data.

192.168.55.0 * 255.255.255.0 U 0 0 0 eth0
any further suggestion? Thank you
Best,
