Murali Reddy commented on CLOUDSTACK-6749:
------------------------------------------
Problem;
-----------
A XE param named 'is-ovs-vpc-distributed-vr-network' for the bridge is set to
true for the VPC's that are configured for using distributed routing. While
this check works in case when there is a parameter, results in exception when
no such param is there i.e) for the bridges not configured for VPC.
Root Cause Analysis:
--------------------------
Exception is not handled, which ends up in the logs.
Proposed Solution:
------------------------
Handle the exception, as it can be handled gracefully, and not really exception
but a condition check.
QA steps:
-------------
In the logs, there should not be any reported exception messages
There is not test case for this bug, and no need for one either.

> [OVS] xe network-param-get with param-key=is-ovs-vpc-distributed-vr-network
> alway returns error
> Steps to reproduce:
> ================
> 1.Bring up CS in advanced zone with xen cluster
> 2.Create physical network with GRE isolation
> 3.Create isolated network with virtual networking and ovs as the service
> provider
> 4.Deploy few vms in the above network
> 5.Observe /var/log/cloud/ovstunnel.log file on the xen hosts
> Result:
> ======
> Everytime when the "xe network-param-get" commnad is executed with
> param-key=is-ovs-vpc-distributed-vr-network we see the errors.
> Following is the log snippet from xen server ovstunnel.log file:
