address@hidden,
I'm use KVM on a Ubuntu Server 12.04 LTS 64 Bit and I try to configure the
bridge completely with libvirt.
The Device eth0 is connected to the lan (192.168.100.0/24)
I generate the file /etc/libvirt/qemu/networks/intern.xml to specify my
network 'intern'
<network>
<name>intern</name>
<uuid>77b879fa-4c04-0cb2-e58a-aef0673806a4</uuid>
<forward dev='eth0' mode='route'/>
<bridge name='intern' stp='on' delay='0' />
<mac address='52:54:00:8F:05:DB'/>
<ip address='192.168.100.1' netmask='255.255.255.0'>
</ip>
</network>
and mark it 'autostart'
My /etc/network/interfaces looks like this:
# The loopback network interface
auto lo
iface lo inet loopback
# eth0 ohne IP für Bridge Variante 1
auto eth0
iface eth0 inet manual
up ifconfig eth0 0.0.0.0 promisc up
I reboot the system ....
ifconfig show me:
address@hidden:~# ifconfig

and:
address@hidden:~# brctl show
bridge name bridge id STP enabled interfaces
intern 8000.5254008f05db yes intern-nic
The problem is that eth0 was not bound to the bridge 'intern' intern.
When I add eth0 manually it will work and I can ping the host from the lan
address@hidden:~# brctl addif intern eth0
[...]
address@hidden:~# brctl show
bridge name bridge id STP enabled interfaces
intern 8000.5254008f05db yes eth0
intern-nic
but why it is not automatically added by this line:
<forward dev='eth0' mode='route'/>
??
