I have a Ubuntu 10.04 server installed on a Dell 1950 with two gigabit ports. I have also installed KVM and bridge-utils.
I have setup a win 2008 VM and it has a NATed network current working. However I want to access the VM server directly from the outside world. For this I want to change it to use bridged networking as recommend.
here is the /etc/network/interfaces file:
auto eth1 iface eth1 inet static address 10.0.1.37 netmask 255.255.255.0 gateway 10.0.1.1 #auto br0 (commented as system was not booting) iface br0 inet static address 10.0.1.44 network 10.0.1.0 netmask 255.255.255.0 broadcast 10.0.1.255 gateway 10.0.1.1 bridge_ports eth1 bridge_stp off bridge_fd 0 bridge_maxwait 0
When I do ifconfig, br0 is not showing up. If I do:
sudo ifconfig br0 up
I get: br0: ERROR while getting interface flags: No such device
If I do:
> sudo ifup br0
The whole system hangs or the network goes out ( I am doing this remotely over SSH).
What an I missing? How do I diagnose the issue?
