Well, so is it reason not to bring up an interface? (Answer is - YES)
I've removed dnsmasq because it was giving away IP addresses, although
DHCP has not been defined in XML. I've mentioned this some time ago in
an e-mail with poetic subj: "dnsmasq, dhcp - bug or feature" :)

Umm thanks for helping me to solve this one, yet I still think it's -
odd. I mean ... you know ... oh well :| (how to put it - head down,
walking away) :)

Have a good night!
