3) Code a xenctl startup script for each IP-based domain to insure
each one is booted properly. For example, "grid-11" should always go
to the same IP address, not a different one if, for example, one of
the other domains fails to start or is accidentally started twice.
For illustration purposes, grid-11.arsc.edu = 137.229.71.11.
The main system, peabody.arsc.edu = 137.229.71.6
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.
