Static IP can't work

[satimis]

Hi folks,

KVM
host - Debian 5.0
VM (guest) - Ubuntu 9.10


Just created a new VM running Ubuntu 9.10 with following command;

$ sudo virt-install --connect qemu:///system -n vm30ubuntu910 -r 512 --vcpus=2 -f /home/satimis/VM/vm30ubuntu910.qcow2 -s 12 -c /home/satimis/Desktop/mini_ubuntu9.10.iso --vnc --noautoconsole --os-type linux --accelerate --network=bridge:br0 --hvm


Internet can be connected with following dynamic IP

$ cat /etc/network/interfaces

auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

If change it to static IP then it can't connect Internet

$ cat /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         192.168.0.30
        netmask         255.255.255.0
        network         192.168.0.0
        broadcast       192.168.0.255
        gateway         192.168.0.1
        bridge_ports    eth0
        bridge_fd       9
        bridge_hello    2
        bridge_maxage   12
        bridge_stp      off

$ sudo ifconfig eth0

Please advise how to fix the problem. TIA


Remark:
Other VMs works seamlessly with above static IP

you are changing the device br0 on the guest, does it even exist? You say dynamic IP works with eth0, then you should be setting that static IP stuff for eth0.

auto eth0
iface eth0 inet static
        address         192.168.0.30
        netmask         255.255.255.0
        network         192.168.0.0
        broadcast       192.168.0.255
        gateway         192.168.0.1

Thanks for your advice.

Other running guests with above setting;

auto br0
iface br0 inet static

work without problem.

Changing them to;

auto eth0
iface eth0 inet static

didn't work at all.
