Description Priscila 2019-07-25 20:43:37 UTC 
Description of problem:

- The VIP 10.X.X.18 is currently in use by VM 10.X.X.34. We can stop keepalived so VM 10.X.0.59 will aquire 10.X.X.18 VIP. The two VMs are otherwise identical
- Stopped keep alived. The .59 VM acquired the .18 IP address. However, it (.18) is still only pingable from the same subnet.
-  The two VIPs are .13 and .18. The .59 has them both now.
-  The publics are not reachable from anywhere - even the same subnet.

We need this in our puppet-vswitch:

commit b6dab2e9bb08401507d95715734f5841663ae055
Author: Numan Siddique <nusiddiq>

    Fix the undefined method 'chomp' for nil:NilClass error seen with ovs 2.10
    
    puppet-ovn uses puppet-vswitch to configure the OVN params. When OVS binaries are
    compiled with dpdk support and when vs_config provider runs the command
    'ovs-vsctl list Open_vSwitch .', the below warning messages are seen and
    are part of the command output.
    
    ----
    PMD: net_mlx5: cannot load glue library: libibverbs.so.1: cannot open shared
    object file: No such file or directory
    PMD: net_mlx5: cannot initialize PMD due to missing run-time dependency on
    rdma-core libraries (libibverbs, libmlx5)
    ----
    
    We see the error 'undefined method 'chomp' for nil:NilClass' when the result is
    extracted. This patch fixes this issue by checking if the 'value' var is nil or
    not before 'parse_column_value' is called.
    
    Tripleo deployment with OVN is failing because of this issue.
