Hello Klaus, There's a couple places to look for logs: - kubectl logs -n openstack --all-containers nova-0 # this will get you logs from nova-api, nova-scheduler and nova-conductor - sudo snap logs -n all openstack-hypervisor.nova-compute # this will get you all logs from the nova-compute service - sudo snap logs -n all openstack-hypervisor # will get you all logs of all services in the snap Can you try from the CLI to get the reason why the VM is in error? openstack server show <id> # might show you the reason why the VM is in error, such as no host found or else Hope this helps you find the root cause, Guillaume On Wed, Aug 21, 2024 at 3:35 PM klaus.becker@webmen.de < klaus.becker@webmen.de> wrote:
Hi OpenStackers!
After a vacation I continue to get my first OpenStack work (one node guided install).
*What works:*
- I managed to install OpenStack on *Ubuntu 22.04.4 LTS *on an older DELL server with plenty of RAM and Disks - I used Snap Install - I can use horizon to create my VMs
*Problem: * After I made a few instances from the Ubuntu templates with different flavors, I am Getting the status „*ERROR*“ for each of these instances. Trying to shutdown an instance I am getting an Error: [image: PastedGraphic-1.png]
*Questions:* What is the *best practice for troubleshooting* regarding my installation type (*single node, snap*)? Where do I find log-files? Google brings different solutions, but the paths and files do not exist for my installation?
*I tried a few suggestions:* Openstack instance generating status error – Fix it now <https://bobcares.com/blog/openstack-instance-generating-status-error/> ( /var/lib/nova/ and /var/lib/nova and /var/log/libvirt/qemu do not exist )
*I found:* ~snap/juju ~snap/openstack
*~/snap/openstack*$ ls -ahl

The link "current —> 560 has no target here!
In „common", there are sunbeam-logs
Maybe there is a misconfiguration with the soft-network. I had a hard time understanding the different networks I need to access VMs from the LAN.
Finaly I found then logs using "*find -name nova*“ /var/snap/openstack-hypervisor/common/log
