I have a static configuration. This is wat I've tested:

iface xenbr0 inet static
       bridge_ports eth1
       address 91.198.178.3
       netmask 255.255.255.0
       broadcast 91.198.178.255

With xenbr0 and without eth1 I have no SSH anymore. This is not nice
because it is a server in a datacenter. But I have also a bad working
remote console. I see this error:
xenbr0: ERROR while getting interface flags: Wrong device

When I have an eth1 and I start xenbr0 I see this:
------
Configuring network interfaces...[   18.279269] xenbr0: Dropping
NETIF_F_UFO since no NETIF_F_HW_CSUM feature.
Waiting for xenbr0 to get ready (MAXWAIT is 32 seconds).
-------
And the connection is gone too.

Yes, I did. I have removed this line:
(network-script 'network-bridge netdev=eth1')
Do I need to remove both network-script and network-bridge?

You can configure it.

Thanks for your help to get it working again.

Met vriendelijke groet,
