Configuring a default network brige when installing KVM killed networking
 
I've just installed SLES 11 SP1 on a test server and installed KVM through YaST. About half way through it prompted me to configure a default network bridge, I clicked yes and lost my VNC connection. I now can't ping either of the 2 interfaces. If bridging renders an interface unusable for normal use how can I tell it to only use one specific adapter?

you can configure the networing manuly or if you want you can remove on of the 2 bridge you created

When an interface is connected in a bridge, no IP is on the interface (you can set an IP in config, but it does nothing).

Virtual machines use bridge very often. The interfaces are in a bridge in host and you can put them IPs in guests.

However, there is a question about IP on the host. You can put an IP on the bridge.

If you really want to delete bride user brtctl command:
brctl delif br0 eth0
brctl delif br0 wlan0
brctl delif br0 vif0
... remove interfaces from the bride br0

brctl delbr br0
... delete the bridge br0

see 'man brctl'
