I added some more detailed output:

When I ping Machine1 ( IP: 192.168.0.135) with Machine2 ( IP: 192.168.0.70)
they are pinging each other.

This is the output:

$sudo ovs-dpctl show
system at dp0:
    flows: cur:3, soft-max:512, hard-max:262144
    ports: cur:3, max:1024
    groups: max:16
    lookups: frags:0, hit:576, missed:86, lost:0
    queues: max-miss:100, max-action:100
    port 0: br0 (internal)
    port 1: eth1
    port 2: eth0

$sudo ovs-dpctl dump-flows br0

When I ping eth0.10 ( IP: 10.0.0.1) with the other vlan interface eth0.10
(IP: 10.0.0.2) they are not pinging each other.

This is the output:
$ sudo ovs-dpctl show
system at dp0:
    flows: cur:2, soft-max:512, hard-max:262144
    ports: cur:3, max:1024
    groups: max:16
    lookups: frags:0, hit:656, missed:89, lost:0
    queues: max-miss:100, max-action:100
    port 0: br0 (internal)
    port 1: eth1
    port 2: eth0

$sudo ovs-dpctl dump-flows br0
tunnel00000000:in_port0002:vlan10:pcp0
mac00:26:5a:75:fa:65->ff:ff:ff:ff:ff:ff type0806 proto1 tos0
ip10.0.0.1->10.0.0.2 port0->0, packets:24, bytes:1440, used:0.874s,

tunnel00000000:in_port0002:vlan65535:pcp0
mac00:26:5a:75:fa:65->ff:ff:ff:ff:ff:ff type0806 proto1 tos0
ip192.168.0.135->192.168.0.4 port0->0, packets:77, bytes:4620, used:1.006s,
actions:1,set_vlan(10),0

It seems that OVS droping the packets.

Thanks,
