The eth1 IP on compute node (192.168.0.11) seems to have disappeared but
 I can still ping this IP from controller. Is this behavior normal?
 
Thanks,
Nishant

Hi Dan,
Just before launching the instance using 'nova boot', I had run these commands on controller (ran only on controller):
# nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
# nova secgroup-add-rule default icmp -1 -1 0.0.0.0/
I assumed that they will configure firewall correctly. Please let me know if I missed something.
Thanks,
Nishant

It may be simpler than that. Did you set up firewall rules to allow ICMP and SSH access to your instance? "Access & Security" then "Security Groups".
