[Bug 1588112] [NEW] instance stuck at error state after trying to migrate it to a misconfigured nova-compute node

 

Public bug reported:

I was trying to add another nova-compute node into the cluster.

Afterwards I tried to do a live migration to verify the configuration.

The instance got stuck at error state and showing the task of migrating.

I then fixed the misconfigure with the new added compute node. But the instance still not got fixed.
(the misconfigure was the network of the server and nova.conf file)

It seems that I can do nothing with but deleting the instance.


some commands and results below:
