[2020-07-17 03:18:12,226] test script return failure 


The Nova compute log from compute-1 is starting from 2020-07-17T03:21:04 , so it is useless for this issue. 

From the test script collect :
compute-0:

conclusion:

This VM tenant1-vm_with_pci_device-1 is using QAT pci_passthrough ,  it is expected migration failure because compute-0 does not have QAT devices.

Thanks.
