Comment 19 for bug 584048

This is my /etc/network/interfaces

eth0 is connected to the local network, eth3 is reserved for the cluster (it's a redhat cluster), domain.it is not the real domain...

I have no autostart network in libvirtd, the /etc/libvirtd/qemu/networks/default.xml is the standard one as installed by lucid libvirt-bin package:

<network>
  <name>default</name>
  <bridge name="virbr%d" />
  <forward/>
  <ip address="192.168.122.1" netmask="255.255.255.0">
    <dhcp>
      <range start="192.168.122.2" end="192.168.122.254" />
    </dhcp>
  </ip>
</network>

But I removed the symlink under /etc/libvirtd/qemu/networks/autostart as I only use br0 bridge
