Comment 1 Masaki Furuta ( RH ) 2017-07-11 10:19:53 UTC 
Hi,

As per comment comment 4 and comment 5 on bz 1393644, can we document how users can modify the templates to remove the constraint for customers who use OVS+LACP with the new kernel.7.3z kernel ?

In order to remove the constraint, delete the following lines from each network interface configuration file prior to deployment:

"""
    constraints:
      - allowed_pattern: "^((?!balance.tcp).)*$"
        description: |
          The balance-tcp bond mode is known to cause packet loss and
          should not be used in BondInterfaceOvsOptions.
"""

Once that setting has been removed from each NIC configuration file, the installer can set "balance-tcp" mode in the BondInterfaceOvsOptions parameter.

Thank you, Furuta-san, for reporting this bug, and my apologies for the delay.

Assigning this now to Mikey for review.

Mikey, see Martin's assessment in comment 7. I'd also suggest running this by Dan (added as QA contact).

Reviewed, merged, cherry picked, and published. Thanks, Mikey!
