In most production situation once XenServer has been installed you may need to do some additional network configuration. The assumption of this document is that only a single NIC is cabled and configured, and that if you are operating with multiple hosts, that the NIC which is cabled and configured is the same between hosts

The IP address assigned for the private network interface must be static. It can be set on the host itself or obtained via static DHCP.

This document will only cover the configuration of a single NIC, multi-nic, multi-vlan, and bonded NIC setups are discussed in the Installation guide
