Generally, the dnsmasq related code is the same, so it should work.

The script in this example seem to operate only on the network
definition file, it misses the actual applying of the changes (or maybe
I missed that in the article).


I didn't try the script itself, but tried the suggested changes for the
network definition, i.e. adding stuff like:

<host mac='de:af:de:af:00:03' name='vm-2' ip='192.168.100.3' />

do the <dhcp> section.

I did 'net-destroy default', then 'net-edit default', made this change,
stopped the dnsmasq and did 'net-start default' (I'm not sure if it's a
bug or a feature that dnsmasq didn't stop, need to look closer into that)
and rebooted a domain. It seemed to work, it got the configured IP
address and the hostname.
