If you are running on recent Ubuntu it appears that you basically need
MULTI_HOST=True set for guest routing to work. Otherwise vhost_net
corrupts the checksums of the dhcp packets, and you're kind of done.
Been trying to narrow this down as far as possible the last couple of
days (as I have some environments where this works, and some where it
doesn't), but I still don't have a specific narrow work around for it
other than turning on MULTI_HOST.

Hi all!
I've been struggling the past couple of days on getting a working
DevStack so I can start contributing to the Heat project. The problems
I've been running into are largely networking related. I've tried a
number of combinations, like using latest git checkouts vs
stable/grizzly for the various projects, and nova-network vs quantum.
The two common behaviors I'm seeing are
1. if I use nova-network, I can't route to the guest VMs at all, with
private or public IP
2. if I use quantum, I can route into the guest VMs, and they can route
to each other, but I can't route out to the Internet (via tthe host
network).
#2 is really close to working, and I wonder if it's just the thing to be
expected. If that's the case, what should I be doing to get the VMs to
be able to route to the outside world? For what it's worth, I followed
the instructions at https://wiki.openstack.org/wiki/QuantumDevstack to
get quantum-on-devstack working. I'm using the single-node setup.
I hope to start contributing a lot to the OpenStack project soon!
