I've tried to setup OpenStrack due to OpenStack cookbook book - on three different hardware - in VirtualBox and without it on baremetal. In every installation when VM boots it ends after:

tun: Universal TUN/TAP device driver, 1.6
tun: (C) 1999-2004 Max Krasnyansky <>

I've tried two different uec images (cirros, ubuntu) and none helped.

There are no errors to be found in any log file. Machine just stops booting and exits.

How I can proceed? On very same box the DevStack installation worked.

Can you post a link to the specific cookbook you're using, and the network related config info you're supplying to it?

Which version of OpenStack are you running?

Hi, I'm the author the first edition which is based on the Essex version of OpenStack. If you'd like to paste some logs to I can see what's up. I've been working on the Grizzly release of the book ( ) which is due for release soon.

Hello Kevin, I have a couple of tar balls for you, one server side and one client side. Sadly the paste saection isn't very useful for this. Do you have anywhere I can upload the tar balls too ? Many thanks Pete

Put them on dropbox or similar solution then share the link to me.

FWIW I'm in the same boat as the OP. Did anyone find a solution to this ?

Many thanks Pete
