Oz network configuration

Network Configuration

With the default configuration, oz-install will attempt to find a suitable bridge to use to do the install. It finds bridges by walking the list of running libvirt networks and looking for one that is a NATed network. If it cannot find one, oz-install will throw an exception.

If it does throw an exception, there are a few ways to fix it. By far the easiest (and recommended way for new users) is to start the libvirt 'default' network:

# virsh net-start default

It is also possible that the default network failed to start because it conflicts with an already defined network in the guest. If the above command fails, that may be what is happening. In that case it is recommended to edit the default network configuration and choose a different subnet:

# virsh net-edit default
change all references to 192.168.122.x to a different subnet (e.g. 192.168.123.x)
# virsh net-start default
