Open Stack

Hi Remo,
Thanks for your answer.  Here is my setup:
1.  Windows 2012 Server with Hyper-V role, getting IP address through DHCP.
 I ran the CloudBase Nova Compute Installer on this machine, and
un-selected the Quantum plugin.
2.  DevStack instance on Ubuntu 12.04, running as a guest on Hyper-V, with
static IP on the same subnet (outside the DHCP range).

I'm loaded my own Windows 7 image into Glance.  Instances come up fine,
with an IP address on the 10.0.0.0/24 network and are accessible using the
Hyper-V console.  I am unable, however, to neither connect from such an
instance to the outside world (Internet or any other machine on my
network), nor ping an instance from any other machine.  I verified that the
default security group in OpenStack allows ping requests and that the
firewalls on the instances are disabled.

I did notice one strange behavior though:  when I try pinging an outside
site from the instance (for example, www.google.com), I can see that the
DNS request was resolved (i.e., it converted google.com to an IP) but the
ping still fails.  Running tcpdump on the DevStack box shows an ICMP
request to the right IP, but no reply.  Needless to say, pinging works fine
from both the DevStack box and the native Windows OS.

Any Ideas?

Thanks,
Yuval
