Sophia, are you sure the diagnostic snapshot is correct? I don't see such failure in logs:

rpodolyaka@rpodolyaka-pc:~/Downloads/fuel-snapshot-2016-07-22_13-33-08$ grep test_create_servers_on_different_hosts . -R
rpodolyaka@rpodolyaka-pc:~/Downloads/fuel-snapshot-2016-07-22_13-33-08$

What are the server UUIDs in question?

[Sofiia Andriichenko (sandriichenko)]

Roman, I was wrong, this correct snapshot http://www.ex.ua/957837273445
