The firewall for the network the hosts are on (I'm assuming an advanced network vs. basic network in CloudStack) neesd to be configured to pass ICMP. You can get to it via the CS gui, start with the networks link and drill down until you find the firewall for the IP in question.

I am having an issue with my servers.  The setup is as follows

_Management Server, Host1 and Host2_
Centos 6.2
Cloudstack 3.0.2

The server was setup by a collegue who has left since but I have noticed that we do not have the ability to send ICMP traffic to our virtualised hosts, prime example being ping. I can see he has setup basic networking, and I do not have the time to try and change this over. I have tried to setup the security policies to allow it but I cannot get any response. Has anyone got any ideas where I should start looking?
