Re: How to work with Flat DHCP Grizzly



Sorry to not answer your private e-mail in time.

I'm quite sure that you'll need at least, two networks but, both private
(according to my guide), one for openstack components, other for Instances.
It doesn't work like OpenNebula as you thought...

You don't need nothing related to "nova network", since we aren't using it.

Ubuntu instance from Canonical depends on a working metadata, because there
is no password preconfigured within the image, you'll need the ssh keys
from metadata, which I was unable to configure it (metadata) within my
environment... Sorry, anyway, you can login into any CirrOS instances via
Dashboard -> VNC Console. Or, you can create your own Ubuntu image using
the command "vm-builder" and upload it to Glance...

Listen, at first, try to follow the my guide line by line, using a new
gateway VM as I told you, to test... Later, after a working installation,
you can start playing with Quantum networks easily...
