[Rdo-list] Single Node Openstack

Usually this is because you forgot to allow ssh and icmp in the security group rules. It's easiest to configure if you use the GUI. Hope it helps.

Subject: [Rdo-list] Single Node Openstack 

Hi, 

I'm trying to learn about how to setup and configure OpenStack. 

I've got a laptop that I want to use a test machine to run a single OpenStack node with instances appearing on the same network as the node itself. I'm trying to follow the instructions from this web site. 

https://openstack.redhat.com/Neutron_with_existing_external_network 

I'm running Fedora 20 on this laptop. 

My network range is 192.168.5.0/24. 

First question, does anyone have a similar setup? Fedora 20, single node, instances on the same network? I can get openstack installed via packstack and everything appears to work except that I can't seem to talk to the instances over the network. At this point I'm stuck and could use some advise on where to look further. 

Thanks. 

-Dave
