In /etc/xenctl.xml, if you write

<nw_ip>137.229.71.0+</nw_ip>
<nw_gw>137.229.71.6</nw_gw>
<nw_mask>255.255.0.0</nw_mask>

would automatically assign IP addresses to newly created domains
based on their domain ID.

e.g. domain N has IP address 137.229.71.N.

However, your Domain 0 IP address 137.229.71.6 conflicts with
the automatic assigned IP address for domain 6. You have to
work around that.

In a typical '/etc/xen-mynewdom', you have:

domain new
domain start

A useful feature of this script is that: each time you run
'xenctl script -f/etc/xen-mynewdom', it creates and starts
a new domain with an 'always-increasing' domain id, i.e.
you run 'xenctl' for the Nth time, it creates a domain with
domain id 'N', even if some previous domains (with domain
id < N) have been destroyed.

Hope this information helps.
