I am brand new to Ubuntu and OpenStack, my apologies if this question sounds a bit simple.

After installing Ubuntu Desktop 14.04, I followed the guidelines of the post to install a single machine openstack cloud.

With the stuff mentioned there, I was able to run cloud-install without any trouble.

I see that it has created several virtual machines functioning as different OpenStack nodes (controller, compute, Neutron, etc).

My problem is as follows - when trying to create a new VM through the Horizon browser interface, I get an error saying the following:

 Error: Failed to launch instance "i1": Please try again later [Error: No valid host was found. ].

I googled around and learned that this error is commonly associated with lack of resources, but that is simply not the case here.

I wanted to see the feedback from the openstack services themselves but I am not able to ssh into the VMs that cloud-install created that are running these services. ((EDIT - to clarify - upon single machine openstack installation described above - it created several VMs, each representing a different Openstack component - such as Neutron, Nova, controller, etc))

How do I get to these VMs? I tried SSH ing with no response, I tried ssh-copy-id to get my public key there, but got a permission denied error. I can ping the VMs fine, they are responding.

So, how do I get into these VMs running the openstack services?
