I looked at the logs and found that there was an error connecting to the View server:
Unhandled error in Deferred:
Unhandled Error
Traceback (most recent call last):
Failure: twisted.internet.error.ConnectionRefusedError: Connection was refused by other side: 111: Connection refused.
Can you make sure you can ping "viewconnection" server from the harness?
Then, you can restart the vdiappd service on harness using (service vdiappd restart).
