[Qemu-discuss] qemu security

[Wolfgang Hennerbichler]

hi,

I've updated from qemu 1.0 to qemu 1.4. One of my VM's used to bridge
traffic (within the VM) between two interfaces. This stopped working in
the new Qemu-Version. It seems as if qemu is blocking traffic as soon as
it sees mac adresses floating on interfaces it wouldn't expect.

I don't have any special network-filters in my libvirt-config:

    <interface type='bridge'>
      <mac address='52:54:00:85:c8:5f'/>
      <source bridge='br0'/>
      <model type='pcnet'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04'
function='0x0'/>
    </interface>
    <interface type='bridge'>
      <mac address='52:54:00:42:e7:5d'/>
      <source bridge='br107'/>
      <model type='pcnet'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x05'
function='0x0'/>
    </interface>

Any help or hints would really be appreciated. Did some default change?
I have a hard time googling...

Wolfgang
