Re: tuntap apparently misbehaving on osx

I don't know if it applies to the dns stuff but to make the http server work 
under Xen I had to add a line

configure interface 'DHCP

In the callback in slides/server.ml

In the case of DHCP there were 2 other glitches which I've sent Anil some pull 
requests for. I guess you want to set a static IP tho ( instead of the 
) - I'm sure I saw a config option for that in there somewhere.
