===== Add a NIC =====

  - Set the XenServer to maintenance mode
    * This will migrate, suspend or shut down any VMs
  - Shut down the server normally
  - Disconnect the power source(s)
  - Reconnect power and start the server
    * Don't start any VMs
  - Scan for new NICs
  - Reboot the server
  - Exit maintenance mode

Scan for new NICs and reboot:

<file>
xe pif-scan host-uuid=<your host UUID>

reboot
</file>
