unable to ping only one instance out of many
I am unable to ping only a single instance although the status of all the instances is "running". I have 3 compute nodes installed and 1 controller node. My first instance's host is my 1st compute node. However, the other instance on the same compute node is not pinging. Why is this happening so?
Could you clarify whether your setup uses neutron or nova-network? Also you may not have a route to ping a VM depending on where you are trying to ping from, so please clarify from where you are pinging.
