<div dir="ltr">I would also like an answer to this question, with the current
networking models of Nova, When i need to assign private IP addresses to

instance via SSH or whatever.<br><br><div class="gmail_quote">On Wed, Feb 16, 2011 at 5:55 PM, <span dir="ltr"><<a href="mailto:J.O%27Loughlin@surrey.ac.uk">J.O'Loughlin@surrey.ac.uk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

All,<br>
<br>
I have a nova install on a single machine, I have launched an instance which I can log into from the compute node, and have associated a public IP address to the instance, see below.<br>
<br>
root@kvm-dev02:~/project2# euca-describe-instances<br>
RESERVATION r-omedt4i6 project2 default<br>
INSTANCE i-00000001 ami-bn6x5xnb 131.227.76.80 10.0.0.3 running mykey (project2, kvm-dev02) 0 m1.small 2011-02-15 22:57:17.803241 nova<br>
<br>
security groups allow ssh and icmp:<br>
<br>
root@kvm-dev02:~/project2# euca-describe-groups<br>
GROUP project2 default default<br>
PERMISSION project2 default ALLOWS icmp -1 -1 FROM CIDR <a href="http://0.0.0.0/0" target="_blank">0.0.0.0/0</a><br>
PERMISSION project2 default ALLOWS tcp 22 22 FROM CIDR <a href="http://0.0.0.0/0" target="_blank">0.0.0.0/0</a><br>
<br>
but I'm not sure about the routing should now work, under eucalyptus the public IP is added as an alias to the public interface and a rule is added to iptables to nat the traffic to the instances private IP address.<br>
It appears nova networking is different, are there any steps I have missed ?<br>
<br>
Any help or pointers much appreciated.<br>
<br>
Regards<br>
