<p>You have a single compute node. The error message when creating
an instance is "no valid host was found". This indicates that, for
some reason, your compute node can't launch the instance.</p>
<p><br>
</p>
<p>The first thing to do is check Nova's status with <i>openstack
compute service list</i>. It will tell you if Nova considers the
compute service on <i>ara-pc</i> running and enabled. If so, you
need to look at the logs. I would start with the scheduler log for
clues why no host could be found, then also the compute log on <i>ara-pc</i>.</p>
<p><br>
</p>
<p>Why your CLI shows a list of containers, but the GUI doesn't: The
first thing I'd check is whether you use the same project in the
CLI and the GUI. <br>

I am quite new to Openstack and faced some issues with creating
instances and displaying created containers on my Openstack
dashboard. I am currently working on multinode Openstack. I am
hoping to get some helps and feedbacks about this. I will
briefly go through the problems I encountered. <br>

When I created a container using both cli and dashboard, two
containers were running. However, when I tried to look into my
dashboard, those containers were not shown.

However, when i try to open my dashboard and look for them, they
just don't appear on it. So I am not sure what is causing this.
