Dear all,

I configure my kvm vm like this:

   <interface type='bridge'>
      <mac address='52:54:00:dd:b2:c5'/>
      <source bridge='nw-vpc-1017'/>
      <target dev='if-57'/>
      <model type='virtio'/>
      <filterref filter='clean-traffic'>
        <parameter name='IP' value=''/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x05'

But when i start it and show the ebtables rules, nothing is applied

[root at kvmhost ~]# ebtables -L
Bridge table: filter

Bridge chain: INPUT, entries: 0, policy: ACCEPT

Bridge chain: FORWARD, entries: 0, policy: ACCEPT

Bridge chain: OUTPUT, entries: 0, policy: ACCEPT

Bridge chain: libvirt_qemu_FORWARD, entries: 0, policy: DROP

Please show me what wrong i've done.
Thanks so much!
Nguyen Thinh
