Hi,

I have deployed OpenStack using Training-Lab. It is working fine but when I have started to lunch instance using image Ubuntu-18.04, it stuck at this stage. The instance remains at this stage forever.

Instance status is active and VM flavor consists of RAM = 8GB, VCPUs = 4 VCPU and Disk = 80GB. I downloaded cloud image from here.

I have successfully launched the instance with Ubuntu 16 image but failed to launch an instance with Ubuntu 18 for one week.

Is there any solution available for this issue?
