Hey Remo,

$> ifconfig -a | grep "192.168.0.11"

The above returns no results.

I have this IP in '/etc/sysconfig/network-scripts/ifcfg-eth1'. Maybe that is why I can ping it from controller?


 
Thanks,
Nishant

Are you sure that no other instances have that ip?

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?
