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.


The first thing to do is check Nova's status with openstack compute service list. It will tell you if Nova considers the compute service on ara-pc 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 ara-pc.


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.

Hi all,
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.

When I created an instances on my dashboard, it directly went into error state. I have attached a screenshot as shown below.

This is my list of hosts.

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.
These are the created containers.
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.


Hope to hear from everyone soon.

Best regards,
Vincent
