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

Please let me know if I missed something. Thanks, Nishant Sent from Yahoo!

Did you set up firewall rules to allow ICMP and SSH access to your instance? "Access & Security" then "Security Groups". +Dan On Dec 19, 2013 12:42 PM, nishant kumar <[email protected]> wrote: > > Hi All, > > I need some help on bringing up my openstack setup.
