What networking are you using? I found Neutron to be unmanageable
and fell back to nova, which worked with my small cloud
implementation. I'm using one control and one compute host, soon to
be 3.<br>
<br>
Can you ping out to local IPs or 8.8.8.8? I'd start with the
interfaces involved on your compute and control and network hosts.
You have to see where the first place you see packets is and then
dump the traffic on each of the ports going out from the instance in
order to see where your packets are getting stopped.<br>
<br>
Are you getting DHCP addresses on your instances?<div><div class="h5"><br>

I can boot my instance and get inside it via VNC console, but

I am assuming its something to do with the way devstack sets up
networking thats probably not working correctly.. just a guess!<br>

My instance boots up fine and has a

Update. I've done a fresh
install and am successfully
running<br>
instances on my compute
host, but, while I can
connect out of my<br>
instances just fine, I can't
get into them from any host
but my<br>
compute host.<br>
<br>
I thought that RDO was going
to set me up so that each
compute host<br>
handled the routing
directly, but it appears
that all of my instance's<br>
traffic is routing through a
bridge to my control host.<br>
<br>
My compute and control hosts
are on a <a href="http://192.168.0.0/16" target="_blank">192.168.0.0/16</a>
network and are<br>
using <a href="http://192.168.20.0/24" target="_blank">192.168.20.0/24</a>
for the instances.<br>
<br>
How do I get traffic routing
into my instance hosts on <a href="http://192.168.20.0/24" target="_blank">192.168.20.0/24</a><br>
on each compute host? (I
only have one now, but will
be deploying 2<br>
more once I have OpenStack
set up.<br>

need some help setting up
my network before doing an
install of RDO<br>
using nova-networking.
I've got 2 hosts -- one
is a control and one<br>
is a compute host. Each
has 2 NICs.<br>
<br>
It's my understanding that
I need to configure the
network before<br>
doing the install, but I
can't find any good docs
on just what I have<br>
to do.<br>
<br>
My initial install allowed
me to create instances
that I could get<br>
into and out of via ssh,
ping, etc., but when I
created a new tenant<br>
and a network for that
tenant, the networking
stopped working.<br>
<br>
I used this command to
create the network:<br>
<br>
"nova network-create
ruby-net --bridge br100
--multi-host T<br>
--fixed-range-v4 <a href="http://192.168.20.0/24" target="_blank">192.168.20.0/24</a>"<br>
<br>
While I found more
documentation for neutron,
I'm not finding much<br>
for nova. I have the
following questions:<br>
<br>
1) how should I set up my
network interfaces on the
control and<br>
compute host for a
nova-networking
installation?<br>
2) where are the docs for
installation (including
such prep as<br>
above), as well as
post-install tenant set-up
for this type of network?<br>
<br>
Thanks for your
consideration.<br>
