Hi Guido,

I've tried your suggestion, it doesn't work.

Whatever, I've found what was wrong. This an ARP issue.
I've dumped network traffic by a tcpdump in libvirtd startup script to
see what happens at network layer. The host send a "who has" and obtains
no reply.

By adding this ugly piece of code in startup (start section) script it
works :

if running ;  then
      log_progress_msg "already running"
      log_end_msg 0
      exit 0
fi
** arp -i eth1 -s 10.10.0.1 00:09:8A:05:7F:2C **
rm -f /var/run/libvirtd.pid
start-stop-daemon --start --quiet --pidfile $PIDFILE \
       --exec $DAEMON -- $libvirtd_opts

Here is my /etc/network/interfaces :

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
        address 194.167.31.37
        netmask 255.255.255.0
        network 194.167.31.0
        broadcast 194.167.31.255
        gateway 194.167.31.242
        bridge_ports eth0
        bridge_fd 9
        bridge_hello 12
        bridge_stp off

auto eth1
iface eth1 inet static
        address 10.10.0.23
        netmask 255.255.255.0
        network 10.10.0.0
        broadcast 10.10.0.255

Maybe there is a parameter to add to authorize arp cache altering during
boot process ? Do you have tips about it ?

Many thanks for your help,
