[libvirt-users] bridge / ubuntu / no arp reply

[François Chenais]

Hello

I'm trying to setup a bridged guest on an ubuntu 13.10 but it doesn't work.

(Everything is ok with NAT)

Network sniffing shows that arp replies don't come back to the guest.


Test 1
------

Guest : ping host_bridge_ip   (ok)



Test 2
------

Guest: ping other_lan_host (KO)

     other_lan_host

            - receives arp who-is request
            - sends arp reply
            - arp -a   shows the guest macaddr


     => Guest doesn't receive reply


Test 3
------

other_lan_host ping the Guest   (KO)

   - arp -a shows "incomplete" addr
   - Guest receives nothing


On Host
-------

network tcpdump on bridge or vnet interfaces shows request but no reply ...


Thanks in advance for help or ideas


    François
