Dear everyone,
In step VM Synthesis,an error occurred.
In log /var/log/nova/nova-computer i saw as follows:
2018-11-14 18:01:50.183 13882 WARNING nova.virt.libvirt.imagecache [req-e90e7524-6c35-4157-afd4-c8e363dfc9b8 - - - - -] Unknown

But there are files in /var/lib/nova/instances/_base, also I found four images in /var/lib/glance/images,
They are the same in size，but different in ID。
When I am synthesizing VM ，what is the problem, how can I solve it?
kind regards
