Open Stack

Hi,

Problem / Mystery solved. I checked my documentation once again and noticed that I used Fedora Core Os 34.x the last time. Once I used the very same version it worked fine. So it seems that something has changed in fedora core os 35. I couldn’t find any hints on which version is supported with magnum but also the latest magnum doc just refers to latest. Still it doesn’t explicitly say do not use version 35. Is there anything known about this?

Best regards,
Oliver

But I think This was on Ussuri back then. I went through the magnum troubleshooting guide but couldn’t solve my problem. Magnum spins up the master node and I can log in via SSH using its floating IP. I checked the logs and saw this after waiting for a few minutes:
