[ovs-discuss] VMs on two HOSTs can't ping each other

Hi,

I am trying to setup 2 OVS Hosts, with VMs running on each. My goal is to
see the VMs can ping each other (I tried the VLAN cookbook and couldn't get
it to work, so trying with VM with no vlan config first). Here is my setup:

VM1 (11.1.1.4) and VM2 (11.1.1.5) running on Host 1.
VM3 (11.1.1.7) and VM4 (11.1.1.8) running on Host 2

Both Hosts showing VM ports are in the br0:

jason1 at jason1:~$ sudo ovs-vsctl list-ports br0
eth0
tap0I
tap1.

Two eth0 ports of the hosts are connected by a ethernet cable, instead of a
physical switch. I had verified that the cable is in working condition.

I didn't assign IP on eth0 of the hosts, as in cookbook.

However, VMs on the same host can ping each other, but not b/w hosts.

I did the same steps as in vlan cookbook, except I didn't use vlan, but
rather the most simple 2 hosts case.

Am I missing some steps? Your suggestions are appreciated!


Thanks!
Yimin
