=head1 NETWORKING AUTO-SETUP
We've already seen how the "gateway" and "netmask" options can
be used to specify the networking options of the freshly created
Xen guests.
One other shortcut is the use of an auto-incrementing IP addresses.
If you specify the IP address of the guest as only the initial
three octets (ie. 1.2.3, rather than 1.2.3.4) then the last
octet will be automatically incremented - and stored for future
use.
The last octet in use will be created in the text file
/etc/xen-tools/ips.txt.
For example if you wanted to create new Xen instances occupying
the IP address range 192.168.1.200+ then you would run:
=for example start
echo "200" > /etc/xen-tools/ips.txt
=for example end
Future creations would then simply use:
=for example start
xen-create-image --ip=192.168.1 --hostname=blah [--dist=...]
=for example end
The first time this ran the machine would recieve the IP address
192.168.1.200. The next time it ran the new image would receive
192.168.1.201, etc. (You could specify "ip = 192.168.1" in the
configuration file; meaning the only mandatory argument would be
the hostname of the new instance.)
Note: There is no facility to "wrap around".
