- If `xm` complains about networking (`vif could not be connected`), it's Xen scripts' fault, see Xen documentation for how to configure the network. The simplest way is network-bridge with fixed IPs (note that you need the bridge-utils package for this). You can also just disable networking by commenting the vif line in the config.
