We have OpenStack implemented on Dell PowerEdge server. The OpenStack cloud has 4 virtual machines running inside it.

OpenStack is running on lxcbr0 interface with IP 10.0.3.X and physical machine on another interface has an IP 172.X.X.X . I am not able to reach (ping/ssh) the virtual machines that are inside the cloud with 10.0.3.X IP series from my host machine . How can I reach the virtual machine instances ? And which software/utility will allow me to access these virtual machines inside the cloud, from an external network ?

When I try ping the Virtual Machines from my host machine I get "Destination Unreachable". Note that I am able to ping other OpenStack components like dashboard, Keystone, Glance etc , although not able to SSH into these components as well. I get a " permission denied : Public Key" error.

Hello, give us some more information about your installation. Nova-network or Neutron, also distribution etc.? Have you created the appropriate rules in the security groups that the VM's belong?

Hi. I am newbie to OpenStack . I have followed the single machine installer on Ubuntu Server 14.04.1 using the Canonical documentation+juju . When I see the VM properties in OpenStack, it has the security rule that allows requests on 22 port from Can you suggest any settings ?

Hi , we have to add two rules (SSH and All ICMP) after creating VM's mostly through web interface dashboard. first of all check whether you can ping to physical machine (172.X.X.X ) from 10.0.3.X or not if the controller is not pinging, run iptable -F command in controller and again try to ping.
