I'm using a public cloud for Openstack and created an instance of ubuntu. When I tried to ssh (or) ping to the IP address available there, it says "No route to host found" and "Host Unreachable". How to fix it?

    Login to instance via horizon and check wether ip address is up by `ifconfig`. If yes assign a floating IP and try ping. – Harikrishnan Feb 19 '15 at 10:33

Are you sure that a DNS record was automatically created when starting VM in your Openstack cloud? You could check this via dig command.

By default all OpenStack environments have security group rules which block all inbound packets to guests. If you want to be able to ssh / ping your created guests you should run the following.

openstack security group rule create --proto icmp --dst-port 0 default
openstack security group rule create --proto tcp --dst-port 22 default

^^^ The above part is from this link

If you get an error for the network name then you can use the id of each of your networks.
