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.
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.
Are you getting DHCP addresses on your instances?

Yup, i did it for the tenant user and admin both, but it still didn't
work :(
I can boot my instance and get inside it via VNC console, but cannot
ping the instance from devstack host and vice-versa
I am assuming its something to do with the way devstack sets up
networking thats probably not working correctly.. just a guess!

I had added the icmp and ssh groups as admin, but had to do it as
well as the tenant user. The docs don't seem to speak to the need
to do things as admin or tenant much, but I had to run both
commands to set up the security group rules for icmp and ssh as
both admin and tenant user.

Just to be clear.. I have added sec-group rule for ssh, icmp into
the default secgroup
and using the default secgroup while creating the instance.. and
yet I am unable to ping and/or ssh the instance from my devstack
host!

I am actually hitting a similar issue with devstack setup on F20
I am able to spawn Nova instances and have setup keypair and
sec-groups and using those key and secgroup while spawning
the instance
My instance boots up fine and has a 10.x.x.x IP.. I can get
into the instance usign VNC.. but cannot ping my host (On
which VM is created) from inside the instnace and vice versa.
I see that sshd is running inside the instnace and doing ssh
root@localhost in the instnace works
So what else am I missing for the networking NOT to work ?
ANy body has any suggestions ?

please excuse my stupidity, but this is the fiftieth time
I've done an install and I had left out the
secgroup-add-rule's for icmp and ssh.
I'm good now!!
I certainly appreciate your help, Yugang.

Hi,
For Nova-network, You can
ping from vm to vm.
ping from vm to internet
You can not
ping from any host to vm exclude host owned vm
You need assign a floating ip to VM.

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

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