Comment 9 for bug 1833622

Hi Peng,

Is it possible to create a normal VM on the your multinode system? I notice that Nova can't connect to database in both ALL_NODES_20190620.210149.tar and ALL_NODES_20190624.161925.tar. If Nova really can't connect to database, no VM can be created.

You can find the log in the following path:
